Joe Corroney is a variant Cover Artist for the 24: Nightfall mini-series. His covers are commonly referred to as "Cover A," while regular artist Jean Diaz provides the cover art commonly referred to as "Cover B." This is his first 24 project.
Corroney's 24 Covers, if fully collected and put together like a puzzle, create a mural with six different portraits of Jack Bauer and a super-imbossed 24 Logo.
Outside of 24, Corroney also does comic art for the Angel vs. Dracula comic series as well as certain Star Wars comic spinoffs.
