"The '70s saw an emergence of art by ethnic artists, notably the Latino group Los Four (Frank Romero, Beto de la Rocha, Gilbert Lujan and Carlos Almaraz), which focused on public art and gave the city many colorful murals and extravagant sculptures. Women artists were always underrepresented, although muralist Judith Baca has certainly left her mark all over the city." pp. 30 - 31.
