Marc Tetro was born in Ste. Anne, Manitoba, Canada, and now divides his time between Canada and a studio in the U.S. His first drawings were inspired by the art of Pablo Picasso during a 1985 exhibition at the Montreal Museum of Fine Arts. He used the T-shirt to create a summer job and at the same time began his artistic career. With his t-shirt art, his goal was to have the viewer understand the image from across the street and this vision continues to define his art style today.

He has been commissioned by organizations as diverse as The Humane Society of Greater Miami, the Royal Canadian Mounted Police, West Point Academy, the Montreal Urban Transit Commission, Walt Disney Company, UNEB Brazil, Kentucky Center for the Arts, the World Philharmonic Orchestra (Concert for Peace), Rocky Aoki Foundation, CanFAR, World Wildlife Fund, Yellowstone National Park and the New York City ASPCA.
