Underground Comix typically have an exaggerated style to their imagery. Famous comic book artists such as Robert Crumb and Gilbert Shelton are known for their over the top style, which not only was good to separate the mainstream comics with their comics, but also to portray certain characteristics in their storylines. For example, if a story involved the use of drugs psychedelic imagery would be present. If a story contained lustfulness or sexual themes, there would most likely be scenes of perversion, nudity or sexual activity.
Facial expressions in underground comics really depended on the mood of the particular comic. For example, if the comic was a humorous title, or was a bit funny and silly in it's nature, the faces of the characters involved would most likely be cartoon like with rounder faces and typical cartoony features such as a huge nose or huge eyes to make them appear wacky or mad. With a comic that dealt with more of a sexual nature, that involved creepy or perverted characters, the characters would usually have more realistic faces but would have dark lines around certain features such as their eyes, mouth or forehead to exaggerate their desperate and sick nature. The images would also most likely be in black and white to compliment the character's sinister and twisted nature.
