1.25" with name of button maker Keystone Badge on reverse along with name of Buffalo "Agent" H.E. Reynolds. Trivial nick off the first few letters of the word "Keystone." Front of the button is essentially Mint and displays pipe-smoking cowboy proprietor superimposed over his saloon-like tavern. Our only other example known from the Hake Collection and from Collectible Pin-Back Buttons exceeded over $300.00. Morry Greener Collection.
