Street Art
Definition: Street art encompasses visual art created in public spaces — often without formal permission — including graffiti, wheat-pasting, stencil art, and murals. It originated in subcultures and countercultures but is now widely collected and exhibited.
Notable street artists include Banksy, Shepard Fairey, RETNA, and Invader. Institutions have begun integrating street art into their programming, reflecting its crossover appeal between activism, urban identity, and fine art.
