The Haunted Fort is a Hardy Boys Mystery Story, number 44. It was originally copyrighted in 1965 as a 20 chapter book. The last books listed on the back cover are "The Mystery of The Aztec Warrior," then the Hardy Boys Detective Handbook," and finally, "The Haunted Fort." I have never seen one of these books where the actual title of the book is also listed as the last book on the back cover.
Since the last books listed on the back cover were copyrighted in 1965 to 1966, we can assume this particular book is a late 1965 or early 1966 print. The front cover is format 5b which was also used during the same period of time. It is the picture cover format, with Ruddi Nappi as the cover artist. The back cover is the earlier "emblem" cover with white lettering without the bold listing of the books. The endpapers are black and white. Between pages 42 and 43 there is a separation at the spine, which is shown in the pictures; however, the book remains intact although completely separated at the spine. This book is offered at a discount due to the spine separation.
