I specialize in this field. I have been involved in cut glass for 27 years. We are having the national convention in New Orleans this year at the Ritz Carlton downtown. I also exhibit at the Corning Museum of Glass every spring and the Dorflinger Factory Museum every fall. Also at the Big Red Barn in Round Top Texas 3 times a year.
If there is something you would like to find in cut glass please contact me. I have an extensive collection and access to many other collections.
