The best-kept secret in town, the 1919 Walla Walla Tractor Show brought thousands of farmers and ranchers to preview and test the latest and greatest technology could provide in agriculture. This book describes the types of machinery demonstrated, the ambitious visions the exposition producers brought to life, and why the exposition attracted many thousands of people.

Blue Mountain Land Trust commemorated the centennial anniversary of the 1919 Tractor Show with the production of a video and this book.
