You get all (16) leatherbound volumes as shown.  Books are never read (essentially new).  The spines are crisp and have not been broken.  Light wear to the books is purely from packing/unpacking from moving.  Overall, these are pristine. I purchased this set in the 1980s, I am the sole owner. 

The copyright inside varies depending on the book, from 1981, 1982 through 1985. Included (enclosed in Hearing, Taste and Smell) is the original publishers letter. There are beautiful illustrations and pictures along with so much research. Titles are etched in gold on the covers on all books. This set weighs 31 lbs, shipping cost will vary by location.
