My dad has a cup that use to be his grandmother’s, who was born in like 1900, and he remembers her having a few of them and some maybe matching plates. The drinking cup looks very much like a blue willow design and it has all the crucial elements in it. However I have not been able to figure out how old or what manufacturer produced it. It is a glass drinking glass and the blue pattern is actually printed onto a white background! There is no water mark or makers mark except maybe an A inside an H on the bottom.
