Book excerpt: Imagine, spread before you, every postcard you ever sent or received. Not only do you see whatever is pictured, but also those who sent and received each card. Signatures, addresses, and even dates recall these friends and loved ones. And the messages themselves, both written and understood, recall the who, what, and where that were significant to us at another time. At so many levels, picture postcards connect us to who we were, and are. This book is a gathering of the postcards of an entire community. Every image within these pages carries a part of the fascinating story of "our town"-Yankton, South Dakota-and the people who have made her what she is.
