Taking its name from U.S. General Dwight D. Eisenhower, who famously wore this type of jacket during World War II, the Eisenhower-style jacket was being sold by postal uniform manufacturers in the late 1940s. It officially became part of the city delivery service letter carrier's uniform in 1953 allowing letter carriers to wear the zippered jacket with its recognizable banded waist instead of the traditional coat. Using the same gray-colored material as the coat, this Eisenhower jacket sports two pleated-patch pockets at breast, buttoned cuffs, ten-inch zipper, and snaps at front. The waistband has two adjusting buttons and button holes at back.
Letter carrier Claybourne Engleman's wore this uniform jacket during the last year of his nineteen years of working at the Bloomington, Indiana, post office, which he left prior to his induction into military service on September 27, 1948.
