Here we have a mass market paperback edition of Under Pressure, by Frank Herbert, published by Ballantine Books in 1974. It is in excellent condition. There is some edge wear, and a few small spider-web creases on the covers. There is some scuffing on the back cover, including one which overlaps the text blurb. There is toning and shelf wear on the edges of the text block, and light toning on the pages as well.
