During the 1960s, psychedelic concert posters became so popular with young collectors that printers quickly began to market them inexpensively. Like the musicians whose work they promoted, artists sought new ways to transform the concert experience using mind-bending explosions of color and lettering that seemingly obscured the intent. Spanish-born artist Victor Moscoso (b. 1936) began creating posters for the Avalon Ballroom in 1966. Family Dog Productions printed this popular poster several times after the concert date had come and gone.
