This is an old EAPG (Early American Pattern Glass) Indiana Glass pattern, Rosette & Pinwheel. This piece is a 52 ounce drink pitcher. It is in excellent condition, and is beautiful. This is the first piece that I have seen in this pattern. I believe that it is pretty rare.
Take a look at the pictures and if you have questions, please e-mail. (I darkened the pictures so that you can get a good look at the pattern.)
