It's BAD for you!
Why do we love things (and sex companions) we know are bad for us? The USA artist (now resident in France) Robert Crumb captures this Mystery sizzlingly.
Devil Girl Choco-Bar used to be a real candy bar, and it was fairly inexpensive, and tasted great. You could buy it in underground comic book stores, where Crumb was / is a major deity.
Crumb's most recognized work is the album cover for Cheap Thrills by Big Brother and the Holding Company (Janis Joplin).
The bio-documentary "Crumb" won an Oscar, deservedly. Crumb specialized in everything the USA tried to hide or prohibit or forget. He was also a champion of forgotten 1920s blues music, and has the distinction of recording the world's last 78 rpm phonograph record, which by that time could be played on very very few turntables.
