Broken Frontier published a two part interview with Michael Dooley, who along with Steven Heller, co-edited the excellent Education Of A Comics Artist.
Michael says: "In it, I talk about comics folks like Kurtzman and Spiegelman, Gilbert Shelton, Robert Williams, and Dan O'Neil, and so on, but I also drop the names of several other Boing-Boing favorites like Emmett Grogan and Abbie Hoffman, Michael O'Donoghue and Lenny Bruce, Colin Berry, and others. I even spend some quality time discussing how Paul Krassner (whose '… Comics Artist' essay includes the Disneyland Orgy story) was one of my primary influences, which I think ties nicely into your recent post about him.
"And if I haven't mentioned it before, there's a page on my publisher's site that has free downloadable information (in PDF format) that we couldn't fit into the book, such as teacher syllabi and an extensive online resources list."
