Hello:
First, could a moderator please change the title of this thread to reflect the discussion? I am very interested in etched glass but relatively uninterested in antique drinking glasses so didn't read this thread until months after it started.
Second, I agree that this is a plate etched design. It is a little unusual in that has been polished to bring out the brightness.
Third, there are tumblers and at least one other size of pitcher available. Every piece appears to have a slightly different scene but the connecting element are the odd looking birds - one flying and one on the ground. The pitcher below is 7 inches tall with a 3.25 inch diameter opening. There is a nice polished pontil mark on the base.
