Mr. Cartoon, born Mark Machado, is a renowned tattoo and graffiti artist from Los Angeles, California. He has become famous for his unique style of black and gray tattooing, with a focus on Chicano-inspired art and designs. In addition to tattooing, he has worked as an illustrator, designer, and entrepreneur, collaborating with various brands and celebrities. The Hundreds is a streetwear brand founded by Bobby Kim (Bobby Hundreds) and Ben Shenassafar (Ben Hundreds) in 2003. It began as a t-shirt line and has since expanded to include apparel, accessories, and footwear. The Hundreds is rooted in the Southern California skateboard, surf, punk, and hip-hop cultures, drawing inspiration from these diverse subcultures to create unique designs. While I don't have specific information about a collaboration between Mr. Cartoon and The Hundreds up to my knowledge cutoff date in September 2021, it's possible that they have worked together or may collaborate in the future. Both Mr. Cartoon and The Hundreds are influential figures in the world of streetwear and urban culture, and a collaboration between the two would likely be well-received by fans of both artists and the brand.
