These antique green pattern glass mugs were made by the U.S. Glass Company, circa 1899. This Splendid eapg pattern is called 'Colorado', aka. 'Lacy Medallion', or 'Jewel'. A marvelous, deep emerald green glass with shiny GoLd highlighting the Ornate scrolling, jeweled pattern all around! DeLiGhtFuL! These are the 4 oz. size glass mugs measuring 2 3/4 inches high X 2 3/4 inches across the rim. This pair is in good condition - minor roughness on the very bottom - No chips, cracks or fleabites on the top rims at all! The gold paint looks gReAt - with very little wear (hard to find!) One mug does have an 'annealing' line/crack inside the handle from time of manufacture which developed as the glass cooled too quickly - the price reflects this manufacturers flaw. It does not affect the use of the piece at all, though - but can be seen if inspected closely. Still a very NiCe pair of antique glass mugs!
