Really a very nice ex lib copy of the 1850 American edition of Cosmos. 2 volumes which I believe were all that was published in this edition. The binding is very tight and not cracked and there is very little rubbing. Foxing is minimal and the pages are bright. Some pencil notation on page 41 and former owners signature on end page of vol 1. I am not a bookseller, so I am not sure of the exact descriptive terms used to assess condition, but except for the crappy ex lib paint on the spine these two volumes are in really excellent shape. The books have been stored in an enclosed bookcase for decades. Buyer to pay shipping USPS media mail. Thanks for bidding.
