Gas & Oil Advertising. Pure Racing Gasoline Porcelain Sign. Long before pay-at-the-pump, Pure was the kind of name you trusted to keep the family car on the road. It’s got the energy of race day, with engines roaring and the checkered flag waiting. It brings back the sound of the bell hose and the smell of motor oil in the service bay. It looks right at home in a garage, a shop, or a game room full of car memories. It’s a nice addition for any gas and oil collection, big or small. Size: 11.75 in diameter. Please see photos for details. Wrapped and boxed for a safe trip. Most orders go out within 24 hours. Hundreds more signs in our store. Please look over the photos closely, as they show the exact sign you’ll receive. For gas and oil, automotive, aviation, soda, and general store signs. Send us a message anytime. We’re always happy to talk signs! Bob’s Garage Signs. Thanks for stopping by the garage.
