Antique Bryce & Higbee Children’s Cup

This RARE antique treasure was passed down to me from my mother’s estate. The company who crafted this EAPG (Early American Pattern Glass) was in business from 1879 thru 1907. There is a minor chip on the bottom that is smooth. Didn’t see it until I began to photograph the item. Size is about 3- 1/2” high c 2-1/2” in diameter. Could this be a cup that I drank from as a young child? I’ll never know!
