It is a universal cross-cultural truth that a primate doing human things is funny. Ergo 'Little Nap' is possessed of innate comedy. That he is riding a custom built mini sidecar combo with a chimp passenger whilst dressed as Napoleon is bordering genius.
Apparently Little Nap was a performer in US circuses around the early post first world war period. There are several other images of Little Nap around, this is the only one I can find featuring a sidecar.
The postcard just sold on ebay. I bid but sadly someone valued it more than I (and I did value it quite a lot!)...
