They are very similar signs, that are both real. If not exact same sign.
I emailed seller to see where he got sign from, and to be sure that he could guaranteed it to be 100% legit and authentic.
"Claims selling for a friend: that came from a private collection and only used description used by owner of sign wrote for him. He claimed he was not a petro enthusiast or antique expert,and bidding will reflect its price.
He did start it at 99 cents and he said I am letting it fly. The seller seems legit but whoever owns sign is looking to get top dollar.
I just hope it runs the 7 days auction and seller doesn't get a BIN and end early. Happened twice in the last month for me.
God Bless everyone.
