Hello. I recently found this interesting pair of wine glasses. They appear to be handmade and have cut and polished windows all around them. The foot and rim of both are also cut and polished. The color is a pretty light blue color. I'm not sure what you would call the color. I was looking through a book on glassware from the Netherlands and these are similar in style to stemware being produced by United Glassworks of Maastricht. I'm very curious to know who made them and when. They are 6" inches tall.
