Rare Vintage 1950s Phillips 66 Salt & Pepper Shakers Gas Pump Advertising.  Original - From the 1950s, these rare vintage shakers stand 2 and 3/4 inches tall from top to bottom, and are 1 inch wide. Decals show vintage wear, as is expected. Both shakers have removeable bases for re-filling and are stamped AVSCO. The salt shaker specifies that the set is from Monpas Oil Co. in Jim Falls, Wis. Plastic colors are bright and vivid. Set is a great piece of history! Sets were sometimes given to customers at the gas stations.
