If you turn to page 105 in this book you will see two extraordinary figures standing and facing each other in a colored albumen print from 1872. They both have bare feet; one wears a light-blue three-quarter length robe, rather like an elegant silk dressing-gown, and the other a similar one of a darker color, with what looks a little like a skirt underneath. They have rather serious expressions on their faces, and medium-length thick, dark, dry-looking hair. They both have upturned mustaches, rather in the style affected by Kaiser Wilhelm II, although not quite as extreme, and they look as if they’ve been painted on.
