Sir John Tenniel - Self portrait

I've copied a depiction of Sir John following his being knighted by Queen Victoria in 1893. It's entitled "The Black and White Knight" and isn't actually sketched by Sir John himself, but by Edward Linley Sambourne. Sambourne had worked for Punch since the 1860s, and took over as chief cartoonist for the magazine following Sir John's retirement in 1901.

I like the irony about the fact that the night depicted here isn't that far removed from Tenniel's own white knight from "Alice Through the Looking Glass", which Tenniel allegedly based upon himself (even though this was a good two decades before his own knighthood). 

Maybe it's just me as well, but I can't help whether Linley Sambourne was deliberately hinting at Don Quixote here as well, with Sir John just about to start charging at windmills.
