Was able to pick these two signs up, in really rough dirt & grease shape. The Mobil sign was used to mix cement on & has a lot stuck to it & looks to be perma-rusted into the mounting. I could use some info on age & value opinions - Also, the tire sign is two sided tin (two signs) mounted on a wood frame with hangers. Wondering if that's original or if I should take it apart. Any ideas on value per sign?? I may sell one if its advisable to take them apart.

Suggestions on cement removal and what to do with this rusted ring would be VERY VERY appreciated. Id love to restore the ring and mount it again eventually if possible.
