Patty, Aloha from Cleveland. One other thing you might review is on this very website. Go to "The Study" link. Scroll down to the bottom, the last section "Miscellaneous". Then click on the Panama Hat, by the article "Collecting Mystery Fiction". There's a great article by Otto Penzler about the very subject. I attended the 2012 Bouchercon (annual mystery writer's convention) and saw a first edition of H.W.A.K. on sale for $250. TXS Lou
