There are 6 books on offer.
The Osprey Fishing.
All of them published in 1975.
Brown/ Tanned (?) covers and edges of pages,  cup rings marks,  marks from removed price sticker seen on some of them.
One book has partings inside, but still tight. It has rather worn spine as well.
Some books have reinforced ( with magic tape) corners.
No loose pages.
Please please see photos.
All as seen.
