Ah, a man of culture, I see . What can I say, I love the classics... the "tiny woman in a cage" trope isn't new - the works of "Atelier Manassé", or "Studio Manasse" in the 1930s is legendary.
(here "Mäuschen" can either mean "mouse" or "darling", so "my little darling/mouse")
Kinda crazy to think they did all that in the early years of photography, without software.
