Bonus features:

"This “expanded edition” now includes three reviews / write-ups of the book, one of them written by Roger Sabin, author of Adult Comics: An Introduction, comics historian and expert, who teaches a course on the subject at UAL Central St Martins. I’ve also reproduced a promotional flyer which was sent out in the mail to garner sales. Other than that the entire story is reproduced exactly as it appeared, with digitally-enhanced scans."
