"Welcome back to Hogwarts," the teaser wrote, with a yellow background and wizard at the ready.
Harry Potter And The Cursed Child premiered in London's West End in July 2016 and proved to be a huge success.
The play's story picks up 19 years after the events of Harry Potter and The Deathly Hallows, and features Harry Potter as a senior figure at the Ministry of Magic while his son Albus Severus Potter is set to start at Hogwarts.
The book's owner was an extra in the film, and was the first person to request his signature. Emma Watson and Rupert Grint also signed the book, which was auctioned by Teesside-based Vectis.
Vectis claim the book's owner asked the actor to sign the now-iconic novel as he sat in a marquee on set at Goathland on the first day of filming. The North Yorkshire village appears in the film as Hogsmeade.
He wrote on Verity Collins' novel: "To Verity, best wishes Daniel Radcliffe."
The actor who portrayed Hagrid in the franchise, Robbie Coltrane, also wrote his autograph on the novel while the film's director, Chris Columbus, wrote "Believe in magic".
The novel's owner, Verity Collins, was having chemotherapy to treat leukaemia. Collins' mother, Valerie Rudd, is selling the book on her behalf.
Rudd, who is selling the book on Verity's behalf, said: "She loved her time there. We would have even paid for her to be an extra. She was a big fan of the books.
“When Verity was 13 she was spending lots of time in the hospital and she’d read the books while she was there. I started reading the first one in the hospital with her."
Her mother continued explaining the story of Verity's part in the movie;
"So when we found out they were advertising for extras for the film we applied straight away, and even though she was having her treatment she was allowed to do it.
“She was about 15 at the time and he would have been about 11. She was with a group of extras, saw Daniel Radcliffe sitting by himself and felt sorry for him so she went and talked to him," Rudd continued.
The book, which has 13 signatures, was the first item Radcliffe had ever been asked to sign; "He said it was the first time anyone had asked him for an autograph."
Kathy Taylor, a representative from Vectis, said the book had smashed its "conservative" €500 estimate; "It's such a lovely story. It's always difficult to gauge the price when something is unique."
"The seller, who now lives in the south, has great memories of her time on the film and the way the cast treated her during a difficult time while she was ill but her mum said recently it had been sitting in a drawer," she added.
"It became apparent when we promoted the sale on social media it was likely to have been signed on the first day of filming on what was the first Harry Potter film, with actor Chris Rankin, who played Percy Weasley, confirming he had signed the book as well."
Pottermore uploaded a post of the four eBook covers, captioning the images;
"Ever wondered where magic really came from? Introducing the Harry Potter: A Journey Through… non-fiction eBook shorts, adapted from the audiobook Harry Potter: A History of Magic and inspired by the British Library exhibition of the same name.
"Swipe to see all four titles in the series, and head to the link in our bio to find out more (including release dates!)," it added.
Four of Rowling's “non-fiction” stories are titled: Harry Potter: A Journey Through Charms and Defence Against the Dark Arts, Harry Potter: A Journey Through Potions and Herbology, Harry Potter: A Journey Through Divination and Astronomy and Harry Potter: A Journey Through Care of Magical Creatures.
According to Pottermore, “In addition to exploring the origins of magic through history and folklore, the eBook shorts will also feature notes, manuscript pages and charming sketches as previously seen in Harry Potter: A History of Magic.”
Each tale is created to teach readers a new Hogwarts lesson, while staying true to the original folklore and magic of the classic book series.
The first of the two shorts, Harry Potter: A Journey Through Charms and Defence Against the Dark Arts and Harry Potter: A Journey Through Potions and Herbology, will be online and ready for purchase on June 27.
The rest of the eBooks are due to be published in the coming months. You can also preorder the entire quartet onAmazon.

Many of us who grew up with the entire Harry Potter franchise remember waiting in those incredibly long queues for the latest book to be released, eagerly sprinted to the cinema for the flicks and desperately trying to dodge spoilers about character plots.
We also know that once it gets rebooted, we're officially OLD. Daniel Radcliffe will always be our Harry, Emma Watson our Hermione, and Rupert Grint our ginger nut Ron.
The actor who played the title role has now confirmed his thoughts that the hugely popular franchise will be rebooted, and we're totally in denial. Please don't do this to us.
Radcliffe spoke toIGNabout playing the boy wizard in the formative film series, sharing his affirmation that "some other version" of the movies will be created in the future.
"I’m sure there will be some other version of it. I know I’m not the last Harry Potter I’m gonna see in my lifetime – we’ve already got a few more in stage play Cursed Child."
The Fantastic Beasts franchise has kept the wizarding world alive (and is allegedly getting five films), as well as Pottermore and Harry Potter World. Radcliffe didn't rule out the possibility of a Harry Potter TV spin-off.
The actor recently revealed that the spin-off would be intriguing especially if it featured the Marauders- the name given to the group of friends featuring Harry's papa James Potter, Remus Lupin, Peter Pettigrew and Sirius Black.
The Marauders gang aren't alive before the final book or movie, the movie would presumably be a prequel. "I feel like there are other stories from that world that you could absolutely turn into a TV series, 100 percent," Daniel told TV Guide.
"A series with the older generation Marauders, that could be very cool." Amen, Daniel, Amen.
“To a certain extent with things like the play and Fantastic Beasts, I think people are still interested in talking to me about it, but nothing’s been happening in that area,” he told E! Newsin May of last year.
“At the moment, I’m very much enjoying playing lots of different stuff.” In an interview with The Hollywood Reporterhe wouldn’t mind reprising his role.
“I’m never going to close that door, but I think I’ll be happy enough and secure enough to let someone else play it,” he said at the time.
Radcliffe's latest role sees him take on the part of a low-level angel in Miracle Workers who must convince God to let humans survive.
Irish actress Evanna Lynch, known for playing Luna Lovegood in the Harry Potter franchise, lost out in the US Dancing With The Stars final despite receiving a perfect score last night.
Despite missing out on the glitterball trophy, the 7-year-old actress received numerous special good luck messages from her former co-stars.
"Evanna, you are in the final! Can we just say this again? You are in the final. I am so proud of you. We love you. We are rooting for you. Kill it tonight, girl," Emma Watson shared in a video wishing her luck.

Tom Felton, who played Draco Malfoy, joked about their differing Hogwarts houses: "Despite all of our differences at Hogwarts, I want to wish you all the very best tonight!"
Emma Watson, Tom Felton, Bonnie Wright, James Phelps, Katie Leung, and Neville Longbottom himself Matthew Lewis all shared good luck messages to Evanna as she headed into the finals of the popular US dance show.
J.K. Rowling also cheered on the actress: “Best of luck, Evanna. Hope you win!” Rowling had been a huge support to Lynch during her adolescence.
Radio personality Bobby Bones was eventually crowned winner, each of the four contestants were tasked with performing two dances: Firstly their most memorable from the season, and then a freestyle performance.
Judge Bruno Tonioli gave Evanna's dance with partner Keo Motsepe high praise, saying; "It was bright, it was colourful, it was quirky."
The duo received a 30 out of 30 for the dance, but unfortunately it wasn't enough to get Evanna the crown.
Any Harry Potter fan worth their weight in chocolate frogs will know that today, May 2, marks the anniversary of the Battle of Hogwarts.
The climatic war between good and evil, which played out in the final book Harry Potter and the Deathly Hallows, was responsible for the deaths of some of the series' best-loved characters.
Every year, JK Rowling honours those fallen soldiers by apologising for their brutal and untimely deaths – and this year is no different.
Tweeting this morning, the author paid tribute to the one and only, Dobby the house elf.
It's that anniversary again. This year, I apologise for killing someone who didn't die during the #BattleofHogwarts, but who laid down his life to save the people who'd win it. I refer, of course, to Dobby the house elf.
'Based on our understanding of the circumstances, the filmmakers and I are not only comfortable sticking with our original casting, but genuinely happy to have Johnny playing a major character in the movies.'
Rowling's statement was met with massive disappointment from fans.
Many accused her of hypocrisy, after penning a famous novel series about an abused boy to then defend someone who is an alleged domestic abuser.
Meanwhile, the adaptation of J.K Rowling's crime books, written under pseudonym Robert Galbraith, will debut on BBC this evening.
Stike tells the story of private investigator, Cormoran Strike, who is hired to to determine whether a fashion model who fell from the window of her apartment did so by her own choice, or if foul-play was involved.
The mini-series is said to follow the book very closely, and even if you are yet to books, Strike will surely excite any J.K Rowling fan.
Strike – The Cuckoo's Calling airs on BBC One tonight at 21:05.
