(#1) The BE cartoon: a bearded fellow — I take him to be a cartoonist (since this is in The Daily Cartoonist) — in a hospital bed, post-simectory
Note simectory ‘the surgical removal of a simian’ — in this case not an actual simian, but the simulacrum of a monkey: a one-man-band-monkey toy. I hadn’t realized that such toys are still being made, but it seems that they are (classically they are wind-up metal — “tin” — toys, but now they appear to be battery-operated plastic, and considerably more durable than the vintage versions; I speak with recollected sorrow over the short life of my very own monkey-band toy, roughly 75 years ago).
