In 1984, in a second significant wave of murals in the alley, Ray Patlan spearheaded the PLACA project to install murals throughout the alley featuring the common theme of a celebration of indigenous Central American cultures and a protest of US intervention in Central America. Topics of the murals included the Nicaraguan revolution, Óscar Romero, and the Guatemalan civil war. This culminated in the addition of twenty-seven murals during the summer of 1985, funded in part by a grant of $2,500 from the Zellerbach Foundation. This art project proved influential, inspiring the La Lucha Continua Art Park/La Lucha Mural Park in New York City the following year.
