This extra large format cartoon print published by the Canadian Royal Air Force in 1944, based on a notation in the print, is a numbered edition drawn and signed by Canadian artist John Duchak (1921-2012) during his wartime service. The publication location is not given. John Duchak served in the Royal Canadian Air Force during WWII overseas as a cartoonist. His work was printed for distribution and education of Royal Canadian Air Force personnel. Duchak was educated in England and attended the Martin School of Art in London. This cartoon and a companion piece, "Range Estimation Gives Accurate Shooting!" also on offer, therefore were likely drawn in Europe based on their WWII subject matter portraying Royal Canadian Air Force pilots in combat with Nazi pilots as the enemy. The Duchak cartoon uses humor and comical graphics to reinforce the Canadian Air Force safety messages to pilots and crew.
