SSP. A nice example of this C. 1950's single sided embossed porcelain sign from Pennzip Gasoline, a product of the Pennzoil company. CONDITION: The field of this sign shows chips to the porcelain and oxidation. The yellow background shows discoloration and staining throughout. The outer edges are concealed by the wood frame, but show minor wear and porcelain loss as well. A seldom seen and desirable example. This is not a standard shippable item and will require 3rd party shipping or pickup arrangements to be made. Condition: (7.0). Dimensions: 48.50" x 23.75"
