You need to keep your eyes on TKMaxx if you're interested in glass.

The stuff they get in is all ends of lines or remainders, sometimes you can get seriously good quality goods there, I've seen Caithness and Mandruzatto for sale there as well as more general Murano; I've also bought some wonderful Beranek.
Of course, there is all the stuff from the far east too.
Often, reasonable looking bits of Chinese glass can come from TKMaxx and can end up on antique stalls at fairs - we need to know what is coming from the far east so we don't get fooled.
This sort of plate has been seen there. It's honestly not any sort of insult.

On the other hand, your is possibly a bit more complicated in design than the things that have been seen there. As John said, the stuff he saw was more geometric.
