Art Glass Plates

I recently visited Chicago and saw an incredible bright blue glass plate (for about $ 300) in a small art galleries. And I do not remember the name! :-( I want to buy it now that I know it will fit in my case ..... but I lost their card and all I can remember is that the store was on the mile beautiful. If anyone can help, it would be great! (not to mention saving me five hours each way to find the place!)

There are lots of art galleries right around the Art Institute of Chicago. it was north or south of the museum? You probably would be best to go the yellow pages and find all the art galleries with an address on Avenue Micigan. Was it the north of bridge over Wacker? It was south of the water tower? You have announced a few details. safest way is to go to yp.yahoo.com and look under the category of art galleries.
