His name is Bryan "Peabe" Odiamar. He's a Chicago-born but Oakland-based graphic designer & illustrator.
He loves bright colors, great illustration, great handwriting, The Simpsons, other 80s and 90s cartoons, comics, graffiti, donuts, tattoos, and Chicago sports. He's had the nickname since childhood. Long story short, he REALLY liked peanut butter but didn't like jelly.
