Women workers applying fabric to Stinson aircraft wing

View of women workers applying fabric to a Stinson aircraft wing. Label on back: "After the skeleton of a Stinson wing has been completed, it is placed in this unique wing jig. Note that it is rotatable, permiting [sic] the girls who apply the fabric to reach their work easily. Use of this jig makes for easy handling of large sections. It assures a smooth paint job and uniform shrinking of the fabric because both sides can be processed at the same time and need not come in contact with foreign objects." Handwritten on back: "Women workers."
