Chris - my mistake. I was thinking of the original Who's Who covers, which Perez only drew some of, and inked even less.
Claude - that was Crimson Plague. It had, I believe, 2 (or 3, depending on how you choose to count them) issues, published by 2 different companies.
The original #1 was published by Quesada's Event (?) comics, and while there was worked completed for at least a second issue (many pages were available on the company's website), no second issue ever appeared. Unfortunately, I don't remember the circumstances that led this situation.
Later, as part ot the Gorilla Comics line, the title was re-launched with a double-sized (? - well, over-sized, anyway, again, my memory fails me) first issue, containing many (if not all) of the pages originally intended for #2. A second issue followed, but, due to financial difficulties, the Gorilla line was shelved.
