Society of the Spectacle (Paperback)
The "Das Kapital" of the 20th century. Look, you don't need a description of the book. It is Capital of the 20th century, okay. You know who Marx is already, and the spectacle is mediating our lives through images. Get a cheap version of this book and drop it in a bin somewhere so someone else can read it. Send it to a prisoner. Don't put it on your shelf so you can look smart, put it in your pocket and treat it like you're smuggling drugs.
