John Byrne's iconic SENSATIONAL SHE-HULK [1989] #1 cover is a simple body-length portrait of She-Hulk holding a comic book, but it's special because she's 'breaking the fourth wall' with her word balloons, talking directly to comic book fans and threatening them if they don't buy her book. The covers of the entire 1989 She-Hulk series parody or lampoon comic books or pop culture to some degree, often 'breaking the fourth wall' at the same time.
