Vintage Mobil Gas Oil Co. Credit Card EXP 11/78 Items are from the estate of my brother. He was a General Motors master auto mechanic for over 60 years. He collected coins, stamps, automobile memorabilia, classic automobiles that he restored, Car Parts for GM Cars, Plastic Model car kits, Diecast Model Cars, Model Trains, Hallmark Ornaments, and other things. I do my best to describe items as accurate as possible. I am listing a few items each day.
