Robert Held has many different kinds of paperweights in his portfolio. It's odd that you should mention him because I was in a huge glass and china shop on Bloor Street in Toronto last week and they had about 75 of his weights and other glass objects for sale.
His weights are everywhere in gift shops in southern Ontario and there's a woman who does antique and craft shows in western New York State (Buffalo/Niagara Falls area and 90 minutes from Toronto) and always has a large display of Held's work for sale.
