Antique Black Starr & Frost Sterling Silver Leather Flask Telescoping Shot Glass

  

Produced by the prestigious New York high-luxury jeweler Black, Starr and Frost, this premium gentleman's field accessory dates to circa 1880 to 1910. This flask features an incredibly clever mechanical design: the central circular metal medallion on the body is actually the flush base of an engineered, multi-tiered collapsible shot cup. When collapsed, the cup rests completely flat inside a recessed pocket within the stitched leather sleeve, perfectly maintaining the flask's portable profile.
