Doris Finley holding oxygen tank for B-29 Superfortress

View of Doris Finley holding an oxygen tank for the B-29 Superfortress bomber at the Hudson Motor Car Company factory. Label on back: "Hudson Motor Car Co., Detroit, Mich. For immediate release. Life-saving tank for Boeing B-29 crews. Many oxygen tanks like the one Mrs. Doris Finley is holding are placed in the three large fuselage sections that Hudson Motor Car Co. is building for the 98-foot Boeing B-29 Superfortress. A double system is installed so that if one line is shot out or fails one will be available. Pressure cabins in the B-29 make use of oxygen necessary only at extremely high altitudes. Portable oxygen tanks attached to parachutes save crew members should they bail out in the stratosphere." Stamped on back: "Released for immediate use by Hudson Motor Car Company, Public Relations Division, 12601 East Jefferson Avenue, Detroit 14, Michigan. Where required, release has been received from proper authority in Army or Navy Public Relations." Handwritten on back: "Women workers."
