Considering that we spotlighted the Clown Prince of Crime, it seems only right that we make a little room for his arch-nemesis -- not that we need an excuse to showcase the work of Paolo Rivera, of course.
Posting on the Muddy Colors blog, the Eisner Award-winning artist walks through his process for a page from his collaboration with writer Ivan Brandon in the recent Batman Black and White #5. As you would expect, it's informative and beautiful (the use of the "curve ahead" sign is particularly clever). He also includes a terrific Batman character study.
