History of Caricature and Grotesque in Literature and Art by Thomas Wright, 1865
This volume is new to me, it has an interesting table of contents, there is a digitized version at Archive.org, but so poorly done it renders it as good as useless.

This looks an interesting book, new to me also.
Looking on Abe I see that it was reprinted in America in 1968, you can get copies for less than 10£.
I spent a couple of hours wikifying the table of contents, and it seems very interesting indeed. I may pick it up one day; its perspective being almost 150 years old gives it an entirely different focus.
There is a new paperback, published 2005 by Adamant Media Corporation, £12.74 on Amazon, I am going to get a copy.
I notice that it is in the bibliography of a book that I bought yesterday – “Dreaming of Cockaigne” by Herman Pleij.
