This album contains images of strap side flasks, mostly colored half pints, pints & quarts that have no embossing. See the Slug Plate Flasks album for images of strap side flasks with embossed slug plates that identified the merchant or store, most were blown clear glass but colored examples make up about 10%, or less, of the population.
