Pontiac Service porcelain sign features the Flintstones. The colorful 12″ sign has vibrant colors that make it stand out, and its type of advertising will fit nicely with any collection especially a “man cave. The brand is Pontiac, which is the most iconic automobile brand. 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. 12 inches in diameter.
