On top of collating the list, we’ve also written a short guide for anyone who’s thinking about starting their own book memorabilia collection. 

  • When looking at collecting items such as books, the completeness and integrity of the item is key. 
  • Memorabilia without its original packaging or books with pages missing for example could significantly reduce the amount of money an item could fetch should the objective be to make a profit.
  • Always check the spine - the spine of a book, particularly earlier collectible editions is key - once you’ve confirmed everything is there, the spine should be your next port of call. 
  • Confirm authenticity before purchasing - when buying any collectible item, whether it be a signed jersey or a first edition Charlie & the Chocolate Factory book, ensuring the item is genuine is of the utmost importance.
  • Looking into pricing data for the books, it shows that an inscribed copy of a book can increase the value by more than 900%, on average. Keeping an eye out for signed books can be the key to turning a good deal into a great one.

Will Thomas of said,

“Willy Wonka is such a classic film, I’d even say it’s at cult status. There’s no wonder why it’s so universally loved. Roald Dahl was such an incredible author with the ability to capture the imagination of both adults and the naughtiest child alike, which is why we wanted to celebrate the 50th cinematic anniversary of one of his most famous stories.”
