I finished Fish Soup a day before I posted about it (review here) and yet I'm still peeking at it now and then for the mice. I'd still frame a print from this if it were available. As it is, I'm going to post some photos of the parts I'm looking at (though not all) because - winged mice! How can you not love winged mice? Or at least these winged mice.
In that illustration the mice are part of a "Trained Mouse Circus," which I imagine was fairly easy to convince the mice to take part in as they seemed to enjoy being fed by people. The cats apparently "took great interest in" the circus. No reports of performers being eaten - we are left to wonder. But do take a look at the expressions on those cats. They are having...cat thoughts.
