Russell Heath Jr., was an American artist best known for his comic book work, particularly his DC Comics war stories and his 1960s art for Playboy magazine's "Little Annie Fanny" feature. He also produced commercial art, two pieces of which, depicting Roman and Revolutionary War battle scenes for toy soldier sets, became familiar pieces of Americana after gracing the back covers of countless comic books from the early 1960s to early 1970s.
