This book may have never materialized had it not been for the spectacular discovery by Dave's father, Howard, on April 20, 1977 of the two rare Hooked Type bannerstones illustrated below. The following is Dave's description of the find; "They were found at a site we often hunted which was especially productive after the flooded Ohio River had washed the bank for several weeks. The river had just fallen when Dad spotted a portion of a bannerstone protruding from the vertical bank approximately six feet below the surface. Having no digging tools with us to further investigate we returned the following day with my two sons, Steve and Michael, and let them excavate the area where the remaining bannerstone pieces were discovered. This piqued my curiosity about bannerstones and what followed was a 20 year journey of discovery and research culminating in this inspiring book."
