Photograph of the Call Building at Third Street and Market Street in flames, a result of the earthquake, San Francisco, April 18-20, 1906. The fourteen-story tower of the Call Building billows smoke from its upper five floors, flames visible on the ground to its left side and in its lower windows. Further down Main Street, rubble that has fallen from other buildings litters the sidewalk. Firemen can be seen attending to a pump and a network of hoses in the street at the center foreground. Legible signs include: "Hale Dental / Teeth Without Plates / Painless Extraction a Specialty" and "H & E".
