Vintage Mid-Century Federal Glass Geometric Block Decanter with Crest Stopper

Mid-century modern barware produced in 1960s to 1970s. Whiskey decanter holding 750 ml to 1000 ml. Machine pressed glassware from 20th century Very good shape. The only flaw that I can see is the rubber on the stopper is a little bit warped. But still works perfectly. Please see other decanter I have listed if you're interested
