Kentucky Derby Glasses Price Guide by Judy L. Marchman (1999, Paperback)

This guide gives you a detailed description of what each glass in each available year should look like. This also lists Preakness, Belmont, and shot, jigger and variation glasses as well. I didn't like however was it's lack of a Travers stakes glass prices. This guide overall, is an invaluable tool for any serious glass collector. Highly recommended.
