Since the publication of the 1st Edition in 1983, this essential reference by the late Emil Pollak and his wife Martyl has transformed the way tool collectors view collecting. By opening the door of discovery to the rich harvest of history that lay behind the maker imprints on wooden planes, the Pollaks began, and led, an ever-growing search for information about the men who made the tools that built this country. This edition adds some 600 documented makers to the previous edition and includes an updated rating system for judging the relative scarcity and value of American maker-imprinted wooden planes. The one absolutely necessary reference that no collector or dealer should be without.
