welcome to the Glass message board, and also welcome for the hunt to find a maker for your
Cellophane Glass vase, (the name coined by Frank from this board, and this website,http://www.ysartglass.com/Ysart/NotYsart.htm
Lots of examples there
Also read these 2 links from discussions on this board,http://www.glassmessages.com/index.php/topic,22153.0.html
The favourite choice at the moment is Bohemian, circa 1930s. I have a couple, nice stuff,
often classified as Monart, but definitely not!
Hope this helps a bit,
We need a signed one or a label
ps was your vase,by any chance , from a Bucks Auction room?
