The last picture is for information only. Cowboys of the American frontier in the late 1800s would mosey into saloons to trade bullet cartridges for a sip of liquor served in a jigger. Canal diggers along the rivers of the American frontier would also be rewarded with a small dose of alcohol. The word "shot" also connotes a small, potent amount. Whatever the tale may be, these copper shot glasses marry history and myth with a design exclusive to nandaimo. Made of pure, unlined copper, the shot glasses are reminiscent of traditional alcohol stills, typically made of copper due to the material's ability to remove the unpleasant tasting sulfur-based compounds from alcohol. They are stackable for convenient storage. Each glass: Diameter 3.25 inch x Height 5.5 inch. EXCELLENT vintage or antique- Tarnished with age. Bring an earthy sensibility to your elegant aesthetic, by serving water, beer or sake in these glasses. A contemporary accessory - use as is or remove tarnish for a glossy or wabi sabi look.
