Large trade paperback, Centennial Edition, of this 20th century classic. Plume, 1993. Intro by the author. Afterword by Leonard Peikoff. 736 pages. Very good vintage condition, nice floppy paperback. It's a chonky boi but this format makes it easy to read. Spine uncreased, which makes me think this is unread! Only shows some minor shelf wear to bottom of spine. The added material talks a great deal about Rand's writing process. Perfect addition to any Ayn Rand collection!
