This is an antique, blue satin glass, swirl pattern, tumbler. I do not know the maker or its exact age, but I believe that it is Early American Patterned Glass (EAPG), which would mean that it dates to the late 1800’s or early 1900’s. If there is anyone out there who knows the pattern, I would love to hear from you.
This tumbler is in very good used condition. Take a look at the pictures, and if you have questions, please e-mail.
