Original Vintage 1970s Sinclair Fleet Fueling Sign Metal Double Sided Gascard. 100% authentic guaranteed Original. This were hanging signs at Sinclair Stations displaying both sides. Great shape for its age. I’ve seen the Sinclair Credit Cards accepted here sign but I’ve never seen one like this before. Feels like Porcelain but it’s not heavy like Porcelain. Original Sinclair signs are very hard to come by!
