Carte de visite portrait: unidentified bearded gentleman in dark coat, ca. 1860s–1870s

A single carte-de-visite-size albumen photograph, head-and-shoulders studio portrait of a balding middle-aged man with a full dark beard, wearing a dark coat, dark waistcoat, and dark cravat or bow tie over a high-collared white shirt. The print appears to be unmounted in this scan, set against a plain album page. No caption is visible. The same image appears again on page 582 — likely a duplicate scan of the same print. The subject is unidentified.
