I came across these really cool signs yesterday.
First one is a Kelly tires sign, with looks like smaltz(reflective sand paint) for the letters.

Second is a Gabriel snubbers sign, not sure what a snubber was?

I'm looking for information on them if anyone has seen them before and know the age of them, and a possible ballpark value...thank you

Snubbers were an early type of shock absorber to smooth out your ride
