Original glossy 10 x 8 news service photograph of the bloody aftermath of the Saint Valentine’s Day Massacre, allegedly perpetrated by Al Capone. The image shows the corpses of five members and associates of Chicago's North Side Gang, who were gathered at a Lincoln Park, Chicago garage on the morning of February 14, 1929. The men were lined up against a wall and shot by four unknown assailants, two of which were dressed as police officers. The reverse of the photo bears pencil annotations, a ‘Chicago Bureau, Tribune Tower’ credit stamp, and a ‘Delmar Watson Los Angeles Historical Archives Photograph’ credit stamp. In very good to fine condition, with pinholes to corners (the lower left corner tip missing), and two creases to the upper right corner. Encapsulated by PSA as an authentic 'Type I' photograph.
