Vintage glass tumble-up for nightstand or bedside table, or your desk. It measures about 7" tall overall, and is in very good condition without chips or roughness.
This is not really very old, probably mid to late 20th century, not an antique. It's a lab glass style bottle with tumbler which does double duty as a cover for the carafe. The hand painted enamel design is very nicely done, pretty blue flowers.
