Book excerpt: Hunters, collectors, conservationists and art lovers will all want this book on their shelves. Dolin's research skills and Dumaine's knowledge of the stamp market come together perfectly to detail the history and collector values of the Federal Duck Stamp. With Everything from production figures and collector values to little-known facts that have remained buried for decades, Dolin and Dumaine show readers that the Duck Stamp program is not only one of the best conservation programmes in the world, it is also the richest art contest. This book crosses the boundaries of collecting, conservation, art and history. It will become the standard by which other books are judged.
