The colors make the sign pop, perfect for adding to a gas and oil or advertising collection. Whether you are displaying this sign as part of your collection in your man cave, shop, bar, or garage, or giving it as a gift, you can also browse my other auctions for more vintage gas, oil, aviation, automobile, motorcycle, and hunting signs. Bright colors w/ porcelain on both sides.
