Pewter Hip Flasks are steeped in history and were first introduced into society in the 18th Century. Originally a pig's bladder was used, hidden under a woman's petticoat and filled with liquor. This little makeshift hip flask would be carried close to the hip, hence the name and the women would smuggle these onto British warships. They were banned in the state of Indiana in the 1920s, along with cocktail shakers, following the Act of Prohibition. You may not know this but during the prohibition, people who used to carry a hip flask were called "hipsters". These days, pewter hip flasks are considered to be highly collectable items.
