This vintage book is probably on a 5th or 6th grade reading level and seems to be directed to boys. It is a former library book, and it has Library markings. It is slightly bent/ askew. The text block is stained. The cover is in really good condition for its age. The tape on the spine with the library identification was removed, and you can see where it was. Binding is very sturdy. It does not seem to have been read very much. See photos for detail
