Trying to figure out this vintage juice set!

Hi, this is my first posting....but I love this website, so I am sure it wont be my last! I found this little vintage juice set at a local garage sale, paid next to nothing for it, but thought it was so cute. But I have looked and looked and can come up with nothing as to whom the maker might have been, and its true age. Any ideas? It is small, the pitcher only stands about 6 inches tall, and the little glasses are like 2 3/4 inches tall. Seems to be a frosted color applied to clear glass. The woman I got them from told me they were old, and had been her mother's. That was all she knew......so any help would be appreciated!
