Glen - thank you for your reply and asking the Boston carnival glass tumbler expert
My first impression was that it was Czech :?
The reasons I didn't think it was American are the open, reverse handle, the modern streamline shape of the jug, and the high mirror finish on marigold.
For my education, what characteristics of the pitcher and glassest makes you say not European and possibly American?
If it is post 1920's American then that leaves few companies that were making carnival glass - the hunt continues.
