This is Katrin's translation.

"With this piece of glass you buy a speciality from the Bavarian Forest, a treasure for the specialist of real glass arts. Design and technology by our artist Erwin eisch."
But others have already come to the rescue, thank-you all!

I do like hearing what Fuhrman Glass had to say. The piece I have, without an E. with manufacturing flaws and wonky bits, is one that makes Saint-Saens "Danse Macabre" start up in my head.
It's like the rib cages of skeltons, all holding hands and dancing around it. I fell in love the second I laid eyes on it. It most decidedly oooozes eccentricity. I don't, sadly, have pics and can't find anything like it online.
