I found a champion sign I've never seen before. ( no pic yet).It looks to be 3'x3' or 4'x4'. It has a rounded top with dependable written following the curved top. It is the classic red & black champion logo. it says serviced here or sold here on the bottom. Not sure if it's porcelain or not. It's hanging on the back wall of someones garage about 5 blocks from me. I want to know what it's worth before I approach the guy to see if he wants to sell it or not. What are they worth?

Got Socony???
