Photograph of a Mexican Hat Dance in front of the Casa de Avila on Olvera Street, Los Angeles, ca.1920. A crowd makes a wall of onlookers in the background as a man and a woman dance in circles around a sombrero that has been placed on the tiled patio. Men in ponchos and sombreros comprise a large portion of the audience. String musicians stand on the steps of the long adobe that is visible in the background. What appears to be a version of the Mexican flag flies in several locations. A telephone pole can be seen in the background to the left.
