Label on back: "Women today are doing their share side by side with the men who build engines for Uncle Sam's mighty bombers and cargo planes. As the Chevrolet Motor Division of General Motors keeps abreast of increasing production schedules, women have earned an important share of the credit for doing a top-flight production job. In one Chevrolet plant producing Pratt & Whitney aircraft engines, this girl is a test cell technician, helping ready this big radial engine for its test cell run."
