Acquired this in an auction and have tried Google to find more information about it, with no luck. The seller found it in his recently deceased uncle’s attic, and didn’t think his uncle had any association with Gulf Oil, or racing. In my mind it’s from the Le Mans era… or maybe from the Steve McQueen movie?

Anyone have any thoughts as to its true origin?
