Of the stories presented here, every one of them except the Candice at Sea story (bottom left corner) was originally printed in the pages of Heavy Metal. The collected Candice, however, was one of the first books that Heavy Metal sold in these house ads, almost from Issue #1. I guess they figured that any book featuring a topless woman on the cover would probably sell itself.
