This is an antique, EAPG, McKee Glass Co., Doric, aka Feather pattern, 48 oz. drink pitcher. It dates to around 1890. I believe that it is hand blown.
It is in very good condition. There are a few minor scratches on the inside bottom of the pitcher, other than that, it is fine.
Take a look at the pictures, and if you have questions, please e-mail.
