These Justice League-inspired Red Bull cans don't actually exist, but maybe one day they will. They definitely look awesome! The designs were created by Diego Fonseca, a New York-based art director, and he calls the concept "The Red Bull Superheroes Project."
"The Red Bull Superheroes Project depicts a playful union between the Austrian energy drink and the Justice League universe…. Inspired by the uniforms of his favorite superheroes from various ages of the comic books."
If Red Bull actually took this idea and ran with it I bet their sales would take a huge jump. I'd probably even start drinking Red Bull again! Can designs sell.
