Hello:
There were three designs registered on February 4, 1880 and February 13, 1880 by the Rochester Tumbler Co. of Pittsburgh, Pennsylvania, USA. Does anyone on this list have glass pieces with a registration mark for either of those days? If so, could you please provide pictures?
I was able to track down a June 4, 1879 registration by the same firm to a bread plate with barley heads and the saying "Give us this day our daily bread".
Thanks in advance for your assistance.
