This sign was found at an estate sale in Lorain, Ohio. The owner collected glass, metal, and paper signs and advertising signs from all of the grocery stores, drug stores, etc that had went out of business or closed their doors in the 1940’s-1950’s. This 14” x 11” glass sign was found in his collection. Below is an excerpt from S& H Green stamps which notes some of the various “stamps” that were their competitors. It looks like Double Owl would likely be a lesser known comp...etitor. S&H Green Stamps had several competitors, including Greenbax Stamps offered by Piggly Wiggly, Gold Bell Gift Stamps (in the Midwest), Triple S Stamps (offered by Grand Union Supermarkets), Gold Bond Stamps, Blue Chip Stamps, Plaid Stamps (a project of A&P Supermarkets), Top Value Stamps, Quality Stamps, Gunn Brothers given by Safeway, Buccaneer, and Eagle Stamps (a project of several divisions of the May Department Stores Co. of St. Louis, Missouri and offered, notably, by May Company stores, supermarkets, drug stores, gas stations, and dry cleaners in the Cleveland, Ohio, area)This would be a GREAT display piece when framed.
