This is such a neat Kendall Motor Oils sign.  We liked it because it is rusted out on the bottom, but had been mounted to this plywood board to preserve it, and it really gave it a new life and look.  It's an interesting sign to us, because it's 31 inches round, painted metal, which is extremely rare in Kendall collectibles, you usually see 24 inch signs, so this one is larger.  The logo like this is from the 1960s era, so that is what we are dating this sign.
