Shelby and Sandy Murphy are artists, USC Trojans — and brothers. The twosome live in Southern California painting bright canvases of cartoon characters, images, and sports teams and athletes they loved as kids.

Since the Murphy brothers began working together nearly 10 years ago, they have developed a large following and have been commissioned to paint for celebrities such as Zac Efron, Nick Cannon, and Sean Kingston . They have also had their art exhibited in cities across the world, from Paris to Dubai. They’ve been asked by collectors to paint athletes like LeBron James and Michael Jordan, and also to paint for teams, athletic venues, and a hospital.

SI Kids spoke with Shelby and Sandy about their art, their process, and what they hope their work achieves.
