All About Boating - Collection of Six Staple-bound Booklets in Clamshell Bx 6-6

Full set of six softcovers in slipcase with light rubs, label removal shadow. Uncommon collection. I really do not understand how this set is still unpurchased. It is an extremely desirable addition to the collection of any boating or sailing enthusiast. I found it fascinating, and I don't even think about sailing or boating. Informative and well as entertaining. Help me find it a home!
