My dad knew a guy that had a small garage that he tore down for him for the wood. there was also 6 big metal shelving units inside the garage that he also let my dad have. well turns out the guy worked for a service station and the shelves were full of old various small car parts. glass taillight lenses, float bowls, clamps, spark plugs, carb rebuild kits. just a whole assortment of cool stuff. and one of the shelves had this small metal sign as you can see. it has the same thing on both sides. I just thought it was too cool. i think the service station must of used it when they caught people stealing gas back in the day.
