“The Pan-Pacific Auditorium opened on May 18, 1935 in the Fairfax District as a stunning example of Steamline Moderne architecture, with its green and white facade and distinguishable fin like towers and flagpoles. Behind the entrance was a wooden auditorium that could hold 6000 guests. The building was commissioned by Phillip and Clifford W. Henderson with the intention of giving Los Angeles a public convention center ‘to accommodate the annual automobile show and a wide variety of cultural, recreational and sports events.'”
