Depression Yellow Sherbet and Under Plate

This is a depression era, yellow sherbet and matching underplate. I haven't listed this before because I cannot find the pattern name or the maker. I have searched all of my books so if you have any information, I would love to hear from you! It is not vaseline glass, but it is yellow and and is in mint or near mint condition. It is iridescent and the sherbet is 3 1/2 inches high and 4 1/4 inches in diameter. The underplate is just over 6 1/4 inches in diameter. Thanks for looking!
