Vaseline Bottoms Up TumblersBy Mark Chervenka
Vaseline Bottoms Up Tumbler
Vaseline is the latest color to be made into new bottoms up tumblers. Original bottoms up tumblers were by McKee Glass Co. Authentic pieces have "Pat 77725" in raised lettering between the nude's feet and the tumbler rim. New tumblers do not have the patent number. The new tumblers fluoresce under long wave black light indicating their formula includes uranium. McKee never made any original tumblers in vaseline glass.
