Anyway, here at left we have two theatrical critters: Hedgehog and Rabbit. Hard to tell when it was taken ~ can't even hazard a guess. Even the style of the coats is likely "costume" and not contemporary.
Who knows who the person in the diving suit is ~ probably a man, maybe her husband? Diving suits of this type were still experimental (Jules Verne made much of them in this era, as did other adventure story writers). I like to think this couple, aside from being adventurers themselves, had quite a fine sense of humor to want to take this portrait, which sort of sets typical classic portraiture on its end.
