"Molds & Models," known around my house as "the blue book," is an indispensable reference to the Breyer collector. Outstanding cross-references and notations on each mold and model make it easy to use. There is an extensive section on the history of Breyer Molding/Reeves International that makes for some fascinating reading as well. Photographs are clear and demonstrate changes in molds over the course of time. I would love to see an updated version, since this one stops at 1997. Along with Felicia Crowell's "Collectors' Guide," this book will help you enjoy and appreciate your Breyer collection even further. (I've been collecting Breyers since childhood.)
