This is a full set of 10 books. They are very readable and usable but are not in perfect condition by any means. I purchased to read and enjoy the pictures as those for the most part are excellent. The dust jackets are in poor condition but have kept the hard covers in good shape. There are some water stains here and there and a few scuffs. A couple pages have been stained as the previous owner put some newspaper articles about the content in them and it left some discoloration on the pages but still easily readable.  If your looking for a complete set and don't want to tie up a lot of money as decorators then this is your set. I'm going to sell on a pickup basis only.. I'm 100 miles west of Chicago on tollway 88. Thanks for looking.
