Vintage Vinyl Pan American Airlines Travel Bag-El Inter American Panagra

Vintage gray vinyl Pan American Travel bag is about 15 1/8" x 6" x 8" deep and looks like it was rarely if ever used. It feels nice and soft not brittle at all and the zipper works just fine. It says " El Inter American" across the globe and there is an airplane pictured in blue below this and then it says "Panagra" also in blue. There are. Couple of black marks in the vinyl I don't know if they'll clean off but I didn't want to try because I didn't want to screw it up.
