en CB01 OFFICIAL. A man with a walking stick and a large black hat is walking along a narrow path in a garden or park. A large Great Dane is running around him. The hat largely obscures his face, which is only visible for a brief moment. It is possible that this is Otto von Bismarck and his Great Dane, the imperial bitch Rebecca "Beckchen." Since the bitch died in 1897, the photograph must have been taken in 1896 or 1897.
