Keystone K-47C

07/31/2009. Powered by two 220 hp Wright J-5 radial engines and one 425 hp Pratt & Whitney Wasp engine, the second K-47 from Keystone Aircraft at Bristol, Pennsylvania, was produced as an aerial advertising billboard. The lower wing was fitted with strut-braced extensions that increased span from 66 ft 6 in (20.27 m) to 90 ft 6 in (27.58 m).

Registered in 1928 as NC5317 to Aerial Advertising Inc. of New York City, New York, USA, a night neon sign was carried on the lower wing advertising Silver Dust laundry soap. Reregistered NR5317, it is pictured here with the extensions removed, wearing a different colour scheme without tiles, while it has also been pictured in this configuration with Silver Dust titles on the fuselage sides.
