Came across a classified for an old Kendall oil sign. Trying to figure out the age. Anyone know if there are any tell-tell signs to authenticate and date the year? Hard to see too much from the photo. It’s a little bit of a drive to check out in person. Also, I was curious if anyone could put a rough value on the sign? It comes with the stand

Early 50s litho.

The condition is really rough. You're really just buying the stand, which is a lot harder to find than one of these signs. I'd only want to be into this for a few hundred. Someone else may pay more but that would be all I'd want to be into this setup.
