Howard Chandler Christy If You Want to Fight! Join the Marines 1915. Provocative young girl used to attract male recruits before the U.S. entered the war. In 1918 305 women were accepted into the Marines Corps Reserves for the first time to fill low-profile clerical jobs freeing men who qualified for active field service for duty in the trenches. Earliest and one of the rarest of the ‘Christy girl’ recruiting series, issued two years before the U.S. entered the war. Rare. 40×30 near mint, conservation backed.
