Q: I have scoured our local library's reference books looking for information on what I'm told is custard glass, but without success. Can you help me?

A: A great deal of information about custard glass (so-called because its opaque color resembles that of custard) can be found in "Keys to Custard Glass Identification, I through Iv" by James H. Gaddis, available for $17.70 for the set of six with a binder to hold them, plus 75 cents postage from Wallace-Homestead Book Co., 1912 Grand Avenue, Des Moines, Iowa 50305. Custard glass was produced in a great many pieces, from tumblers to toothpicks to spooners to salts.

Q: I have a complete set of green Depression Glass dishes. I don't know the name of the pattern but it seems to be designed like fans and flowers. Where can I sell this set?
