Private Abian A. "Wally" Wallgren worked as a cartoonist for the Philadelphia Public Ledger and Washington Post before the outbreak of WWI, when he served in France with the Fifth Marines of the First Division. Wallgren's cartoons appeared in every issue of The Stars and Stripes, poking fun at army life, satirizing the absurdity of army regulations, and highlighting the differences between the army brass and the frontline soldier. Numerous trips to the war front gave him material for his cartoons and first-hand experience about what soldiers considered humorous. His popular cartoons were collected in "Wally: His Cartoons of the A.E.F.," published by the newspaper in early 1919. Following the war, Wallgren worked as a cartoonist for the American Legion Magazine. In 1933, with former editor John Winterich, he published "The A.E.F. in Cartoons."
