I copied your image and emailed it to the group working on the Bohemian glass website with me.... and got some responses....
This is indeed by Loetz, and quite rare. I located an archived auction listing and in March of this year a set sold on ebay Ireland by a London seller, pitcher and 6 glasses for £920. Same set, same colors. The set was designed by Richard Teschner and is design number 4506 in the Loetz archives. It's design was series II production and appears for the first year in 1908. I am attaching a copy of the design image and hope it can stay.....
What a fabulous find..... :chky: :chky:
I knew I had seen it before, it is just so uncommon I could not remember where....
Edit in: One of the things I love so dearly about early Bohemian glass is that so many of the colors, designs and shapes were decades ahead of their time... I think this is a super example.....
