This horizontal black-and-white photograph depicts a three-story masonry building with several distinct storefronts at street level and residential windows above. The upper floors feature two sets of prominent bay windows on the left and right, with flat windows in the center section. A horse-drawn delivery carriage is parked on the street in the foreground, positioned in front of a central entrance labeled with the word "ROOMS". The storefront to the left features a sign for "ATHENS RESTAURANT," and the storefront to the right has text on the window that includes "CONSTANTINOPLE CAFE". A utility pole stands on the sidewalk to the far right, and various signs are posted near the base of the building, including one with the text "671 MISSION ST." and another for "Richards". The photograph is bordered by a white frame and set against a dark background, with the text "Regal Hotel. 515 Third St." printed in white sans-serif font above the image. A small color and grayscale calibration strip is visible at the very bottom center of the frame.
