Thank you very much for your reply, information and the link to the Tango Glass exhibit pages. Yes, it's nearly impossible to read the captions on the display cases, esp. the one that contains the vase you've posted. Beautiful piece; love how the threads wind around! Love your "collection" esp. the ceramics!
Well, I have a mini-collection, three now, of Czech glass (at least I think the other two in front are Czech, too)! Here's a photo (don't have other views)
