Here is a scan of my 1953 Mars Gas Saving Stamps booklet. Mars was based in the St. Louis, Missouri area. If you see any Mars stuff, please let me know by PM or email.
While we're stuck at home because of the coronavirus restrictions, I'm organizing some of my collection that hasn't seen the light of day in years. I think I have other gas station stamp books somewhere. I'm enjoying this and will probably post scans and photos as well as hang some items up on the wall if I can find the space.
