Collectible Penguin Twentieth Century Classics edition. Book is in solid condition. No dog ears or tears. Heavily annotated in margins and underlined passages. Top and bottom outside edges clean. Outer side edges have a few smudges. Creasing along outside of spine. Cover shows moderate shelf wear on edges and light creasing on corners. Completely legible to read and I always find it interesting what the reader before me thought important and/or interesting enough to underline or comment in margin especially with such a controversial book.
