In honour of Dahl, the Royal Gibraltar Post Office issued a set of four stamps in 2010 featuring Quentin Blake's original illustrations for four of the children's books written by Dahl during his long career; "The BFG", "The Twits", "Charlie and the Chocolate Factory", and "Matilda". A set of six stamps was issued by Royal Mail in 2012, featuring Blake's illustrations for "Charlie and the Chocolate Factory", "The Twits", "The Witches", "Matilda", "Fantastic Mr Fox", and "James and the Giant Peach".

During the Second World War Dahl was a pilot in the Royal Air Force (RAF) until he crashed in the Libyan desert; the subsequent injuries left him unfit to fly. He was posted to Washington as an assistant air attaché, ostensibly a diplomatic post, but which also included espionage and propaganda work. In 1942 the writer C.S. Forester asked him to provide details of his experiences in North Africa which Forester hoped to use in an article in "The Saturday Evening Post".
