These are really neat, original 1940's-50's Texaco Sky Chief Gas Pump Salt & Pepper Shakers.  These you would find at Texaco Gas Stations across the country, SkyChief was there High Octane Gasoline, originally introduced in 1938.  These are really cool, different Texaco Dealers on each one.   Original Box, with a couple flaps missing on one end.   Bottoms come off each end of the Shakers.  Made by Ausco Inc, Kansas City, MO.  Nice condition overall, super nice for your collection!
