I'm trying to track down a few examples of George Edward "Chat" Chatterton's World War II cartoons, especially some from the "Chad by Chat" series. The cartoon character "Chad" is thought by some to be the original image to which the phrase "Kilroy Was Here" was attached. George Chatterton was a British cartoonist who served with the RAF as artist-photographer (1938-50) but began drawing for magazines and newspapers in 1932, contributing to Blighty, Weekend, Weekly News, RAF Review, Boy's Own Paper, Daily Mirror, Dail Sketch, Everybody's, Leader, London Opinion, Picturegoer, Weekend Mail and others. "Chad" was immensely popular during World War II and was featured looking over a wall in a series "Wot! No . . .?" One sighting, on the side of a British 1st Airborne Division glider in Operation Market Garden, had the plaintive complaint "Wot, no engines?". I'm also seeking a photo of George Chatterton. References to books, magazines and/or online sources would all be appreciated. Many thanks!
