I am hoping that someone will be able to tell me the country of origin and approximate date of manufacture of these small blown glass mugs.
I've accumulated forty or fifty of them over the years, have them in several colors, as well as clear, with varied decorations and inscriptions. Height of most is around four inches, although I have several that are about half that size, and one or two that are significantly larger.
Will ne grateful for any information that anyone can provide.
