This is a lovely vintage cranberry carnival glasstumbler from Imperial Glass. The imperial hallmark is present on the bottom of the glass. it is faint, but can be seen with naked eye and better upon magnification. i was unable to get a photo of it - but it is there. It looks like the picture of the hallmark i have included in the photos. Glass measures approximately 2 3/4" in diameter at the top and 4 3/4" tall. It has a flashed cranberry color with a raised design depicting a pond scene with cattails and waterlilies. Color and design are both in good vintage condition and there are no chips or cracks.
The Imperial Glass Company was founded in 1901 by Edward Muhleman, with production beginning in 1904. The handmade glasswares were sold worldwide and were usually made of pressed glass patterns. The factory located at 29th Street was labeled as one of the largest glass factories under one roof. The company's most famous product is their "Candlewick" series, which even has a street named for it in Bellaire.
The company hit rough times in the early 1970s and was close to bankruptcy. Imperial was saved by Lenox and turned to general manufacture, but low demand eventually led to its closure in 1984. The building on Belmont Street was eventually turned into a museum housing many pieces from the company's long run, as well as a history of the company.
