Cheech Marin has been a celebrity for more than 40 years. His fame started when he was part of the pot-smoking counterculture comedy duo Cheech and Chong.

Since then, he’s done some acting in television and film. But in his private life, he’s become a well-known collector of Chicano art. Marin helped kick off five new exhibitions in the Mesa Contemporary Arts Museum.
