Ray's Copy of The Gremlins by Roald Dahl

Roald Dahl's wartime story The Gremlins was developed by Walt Disney but it never made it to the big screen. The tale was instead published in 1943 as a book with illustrations by Walt Disney studio artists from the unrealized production. A fan named Ray acquired an original drawing by Disney animator Bill Justice—along with a mock apology—in his copy of the book.
