An extraordinary unsigned, untitled high-resolution albumen print of Harvard Square, Cambridge, Massachusetts, ca. 1870, when Harvard Square was still paved with cobblestones and the trolleys were horse-drawn. Looking towards Harvard Yard, one sees John Ford & Son, Printers, and, on closer examination of the background, several other printers. The image measures 18 cm x 23 cm, and the mount measures 28 cm x 35 cm. The image is in a very fine state of preservation. There is a small chip out of the left side of the mount 1.5 cm x 3 cm, not affecting the fine image at all. Evidence of a crack in the glass negative is visible in the lower left-hand corner of the image. The technical expertise evident in this unsigned image indicates it was taken by a professional photographer, possibly by John Wallace Black (1825 – 1896) or his sometime partner, John Adams Whipple (1822 – 1891).
