From the LA Times Culture Monster blog: "Frank Romero, a noted muralist and pioneering Chicano painter, is suing Caltrans for painting over a mural he created along the Hollywood Freeway downtown in conjunction with the 1984 Olympics. ... Romero's suit, filed Thursday in Los Angeles Superior Court, contends that sometime after June 1, 2007, a Caltrans work crew painted over his 102-foot-long, 20-foot-high mural, 'Going to the Olympics,' erasing it from a wall at Alameda Street."
A similar federal lawsuit by Romero (mentioned here back in December) was recently dismissed, on sovereign immunity grounds.
