This week's free preview is a downloadable 25-page excerpt — the entire first chapter — from the upcoming expanded and revised softcover edition of Rebel Visions: The Underground Comix Revolution 1963-1975, the definitive history of the era by Patrick Rosenkranz. These previews are exclusive to registered Fantagraphics.com users, so sign up and/or sign in to view.

(As a reminder, 20/20 Club members receive these previews two weeks before we post them on the website, just one of many great reasons to join up...)
