I don't have much gas and oil stuff but here are some of my favorites.. The Keith Gasoline globe is from a small oil company that I was told was from New England.. They were later bought out by Sinclair..
The Crescent sign is from am oil company based out of Baltimore. This company started life as the Red "C" Oil Company, pre 1900.. The Wizard Gas globe was Red C's gas brand, notice the red "C" in the background.. I don't find much Red C or Crescent stuff so when I do it's always a great find..
