Description

Hello, this cool double sided flange sign is pretty cool it would’ve went on the middle of the pump I guess so both sides could see this sign, I believe it to be enamel may be porcelain, not sure, at any rate it’s about 7 inches long and about 3 inches wide,  and would make a great addition to any gas collection, thank you for looking have a great day, also I have two others for sale, thank you.
