You are bidding on the Ace paperback edition of PKD's "The Preserving Machine". Unknow publishing date on this edition. Nothing stated. Please see the copyright pics for better information. 
The book is in excellent shape. There are a few tiny dings to the top edge and  some light corner rounding. A very small amount of wear to the top and bottom spine edges. (see pics)

All books are shipped and stored in mylar bags and come from a smoke free environment.

Winning bidder agrees to pay 10.50 priority mail shipping and packaging. The reason for the higher pricing is one because the post has raised prices and two, I want your books to arrive in the same condition that they left in. I will be happy to combine shipping so please check out my other listing for more vintage and rare Sci-Fi titles. Good luck.
