I am selling my entire collection of Hardy Boys book as well as some other books in my collection. The Hardy Boys collection consists of over 220 different books and 1 or 2 duplicates. The collection includes early books from the 1920s through the later picture cover books of the 60's and 70's and all in between. There are 1st editions, harder to find variations and examples of all the different dust jacket art, spine types, book boards and end papers and even story revisions. Information on each book that I provide comes mostly from the fine guide, Hardy and Hardy Investigations 6th edition by Tony Carpentieri and Paul Mular. If you are looking for a certain book for your collection or just readers for your kids or grandkids, check my listing periodically because it will take some time to get all these listed and I will do it randomly. All my jacketed books are protected by Mylar, done by me or a previous owner. I'll combine shipping if requested.


This is The Secret Panel, the 25th title in the Hardy Boys series. This is a picture cover edition. I am unsure what year this was printed because it was undocumented in Hardy & Hardy Investigations up through the 6th edition of that guide. It was surely printed in 1972 late, 1973 or 1974 early. The '72-'74 printings listed in H&H all have Christopher Cool 1-6 as the last entry in the book, while this copy does not have CC at all, but has a Hardy Boys order form instead. This mystery may have been solved if you have a later edition of H&H. If so, you can send me the info and I'll update my description. he artwork on the cover is the 2nd art used. It is done by Rudy Nappi. The other illustrations are drawn by George Wilson. The endpapers for this book are black and white multipics and the text is the revised version.

This book is in excellent condition. The top and bottom corners of the back board and the top and bottom corners of the spine, all show the tiniest specks of white wear but no other signs of wear can be seen.  There are no marks inside on pages or endpapers. The binding is crisp and feels new. There is a original vendor price sticker on the front cover. 

H&H 6th edition does not have this book listed. To help you see where it may fall, I named it The Secret Panel 1973A/B- 44.5
