I had forgotten all about those jelly jars that became table glasses..... Of course; there's a lot of stuff that I've forgot. I recall the milk man making home deliveries in that little, boxy van style truck made by Divco, ( an acronym for - Detroit Industrial Vehicle Company). Home delivery of milk was to your milk box usually out on the porch. It was a thinly insulated box with an outer skin of galvanized (?) steel (?), or was it some kind of aluminum ? Later on, circa 1967-68, in high school when I was pumping gas at an Atlantic gas station we gave out S&H Green Stamps to gas customers.
