View of a Nash-Kelvinator seaplane in flight. Label on back: "Motor car maker to place giant flying boat in mass production. This mammoth sea-going flying boat, the long range of which is a military secret, will transport military supplies to the far-flung war theatres of the United Nations. It will be manufactured on a mass production basis by Nash-Kelvinator, former auto and household appliance manufacturing company, which rapidly is becoming an important unit in the wartime aircraft industry. The famous Vought-Sikorsky airplane works have made two such four-motored flying boats to date by the hand-made methods, and Nash-Kelvinator engineers have just finished production plans to make the plane on a mass production basis. Press Bureau, Nash-Kelvinator Corporation, Detroit, June 10, 1942." Handwritten on back: "Aircraft in action."
