It fascinates me though that you should have a piece, Brian !
For comparision ? Just becuase you just like it ?
I bought it about seven or so years ago. The piece I have I truly love. It's a copy of a wonderful Loetz vase. If it was real, the value would be, well let's just say I could probably take the rest of the year off comfortably ;-)
But honestly I bought it mostly due to the curiosity of what their glass was like, and felt it was important to acquire an example as a Loetz and Bohemian glass collector.
If my memory serves me correctly it was all of about $80. It came in a nice box that had their factory logos all over, and a little card (in Czech) telling about the company. It's also signed on the base Muller, with a silver foil sticker too, so their definitely not trying to pull the wool over on anyone. I suspect this is either happening later by someone else, or maybe they will sell their pieces unsigned if requested, I'm not sure.
