Circa 1950's this special carving on the Fostoria Crystal blank consists of only "1" Thunderbird on the outside of this tumbler. It is definitely a Fostoria carving & tumbler, although I could not find this obscure cutting in my library of reference books. The "Fostoria" logo is acid etched under the foot. The tumbler is 4-7/8" (H), 3" (W) wide at the rim & 1-1-3/4" (W) at the foot. It holds 12 ounces. Condition is excellent without chips or cracks. There are 8 available but they are priced each. We will discount shipping & insurance for multiples ordered and refund after mailing.
