In 1973, Chicano Park's "founding lead artist" Guillermo Aranda and "founding apprentice artist" Ernesto "Neto" Paul (San Diego, CA natives) collaborated with the art students of the University of California, Irvine (UCI) in painting a mural (approxitmately 8' x 36') on the walls of the Tlatepaque Restaurant. Aranda was invited by a Professor at UCI. The following year the chairman of Toltecas en Aztlan, and the board director of The Centro Cultural De La Raza, Guillermo Aranda, also invited these same Orange County artists referred to as the "Santa Ana Muralists/Santa Ana Artists," to come to Chicano Park and paint on one of the first pillars (2nd painted pillar) of Chicano Park.
