This photo was taken at the groundbreaking ceremony for Grauman’s Chinese Theater, , Hollywood Blvd, January 1926. From left to right, we have Sid Grauman, Charlie Chaplin, Norma Talmadge, Conrad Nagel, and Anna May Wong. What’s interesting is that it appears to be taking place at night, so I’d say it was largely ceremonial rather than actual. There also appears to be a crowd behind them, also dressed in traditional Chinese garb.
