‘An incredible author’

Will Thomas, from LoveAntiques.com, 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.”

Sold more than 250 million books

Roald Dahl was a British writer whose books have sold more than 250 million copies around the world.

Dahl, born in Wales to Norwegian parents, served in the Royal Air Force during WWII and it was in the 1940s that he rose to prominence as a writer.

While he has written a range of works for adults, he is best known for his children’s stories.

Dahl passed away on 23 November 1990 at age 74 from a rare cancer of the blood called myelodysplastic syndrome.

He was buried in the cemetery at the Church of St Peter and St Paul, Great Missenden, Buckinghamshire in England.
