My book has Gutter Code H44 on page 403 and the dust jacket painting matches one in the existing listing. But the back has 2051 and not the alpha code. The artist on my book back flap is the same as the ISFDB listing. But there is not an entry for gutter code H44 or the catalog code 2051 on the back flap. Can you help me. It does have BOOK CLUB EDITION on front flap. - Thank you, Wanda Cronauer
