Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums Known & Suspected Unmarked Petro Reproductions Gulf Tire & No Nox Signs. Real deal?

Both real. Gigantic pile of those No/Nox turned up in the last few years. No-nox=$60-$80 Inserts vary , other than "Gulf" yours doesnt have much going for it. Still, just guessing, Id say $35-50?
