Artist Judy Baca is best known for The Great Wall of Los Angeles (1976–83), a mural that presents a multiracial history of California. The project—involving hundreds of community youth and artists in its conception, realization, and recent restoration—exemplifies Baca's distinctive approach to creating public art. Art historian Anna Indych-López recently published a dynamic account of Baca's "public art of contestation," and discusses with the artist how collaboration and authorship, and issues of race, class, and gender, have influenced and sustained Baca's practice.
