Duncan & Miller Glass produced their famous Teardrop pattern from 1936 to 1955. Usually sizes are pretty consistent within an old glassware pattern, but in this case, there appears to be 3 different sizes and a couple of different names for what I would call a sherbet. Replacements list the sherbet as slightly smaller than the 2 sizes of what they call sundaes, which I have also seen called ice creams. These 2 ice cream sundaes are nearly 4" tall and price is for the pair.
One is in great vintage condition, looking like it was seldom used, while the other one has a tiny flake near it's rim, which truly does not detract from it's beauty or usability. Would be happy to try and catch this blemish in a picture for you.
