NOTE: Sid Lethridge 2021 - These items are all small novelty pieces and are signed with a B in a Diamond. It is a good idea to get familiar with them as they are often found in antique malls. Some of these originated at Degenhart's Crystal Art Glass going back to the 1950s. At some point in the 1970s, Degenhart started to mark their glass with a D in a Heart.
