This wrapper is a work of art created by R. Crumb that was sold in theaters when the "Crumb" documentary made its run. As I recall, the candy was pretty good, and how can you beat this wrapper? I wish more artists did work like this, creating art as a product accessible to the masses in venues where one wouldn't ordinarily expect to find it.
As it turns out, I recently found this tin of Devil Girl Hot Kisses. It has a 1997 copyright, suggesting that it was probably first distributed in theaters as the Choco-Bar was. It's a particularly spiffy little tin, with the words, "Have Yourself a Sweet 'N' Hot Little Suck!" on the side. It was filled with those tiny cinnamon hearts you get for Valentine's Day. I seem to have an allergy to cinammon candy, but I couldn't resist eating a few. They're burning a hole in my stomach as I write.
