Brazilian-born Sergio Cariello has been an accomplished artist since childhood, drawing a regular comic strip for his city's newspaper at age 11. He spent many childhood hours poring over The Picture Bible (Portuguese edition), never dreaming he would illustrate an updated edition (The Action Bible) decades later. Sergio has worked for Marvel Comics and DC comics and has illustrated Batman, Spiderman, Superman, Iron-Man, Wonder Woman, Fantastic-Four, and dozens more comic book characters.
