I don’t usually list books in such rough shape but I’m making an exception for this one since there aren’t many copies available on the site. This is an older copy from the 70s. Has a ThriftBooks sticker, some yellowing due to age, and possibly a bite out of the back cover. I’ve added photos for reference. The pages appear unmarked and the book is perfectly readable. If you need or want to read this and don’t care what it looks like, this is the copy for you!
