Andy Warhol was an American artist who was a leader in the Pop Art movement in the 1950’s and 60’s.This visual art movement was a challenge to fine art traditions because it focused on elevating everyday items from popular and mass culture to be seen as art.
You have most likely seen his art or the influence of his art without even realizing it. (He's the guy famous for the Campbell Soup Cans...but we are going to focus on his portraits of famous people - for which he was also well known!)
