Vintage 1960s Swallow Brand Glassware from China - Set of Four

Handsome Delmonico sized cocktail glasses (the size between a highball and rocks glasses) with reverse scalloped edge base and light cut lines diagonal on the body in the glass, made from what the brand refers to as "toughened glass" - these are relatively thick for barware, and have either been lightly used or never used because all four still have their stickers. Wonderful condition and a rare find.
