This fascinating work of social history examines exactly what the title says - Punch's changing views on wartime Lincoln through essays, poetry and cartoons. It's not just a look at British attitudes (the author, an American, claims Punch was "the mouthpiece of the mob") but also how a comic publication negotiated the changes in the war from both moral and nationalist perspectives (British neutrality and debt were apparently key concerns). Viewed purely as political satire/commentary it's interesting how much is still the same (editorial cartoons, broad humor) and how much has changed (there may be more poetry here than in a current issue of Poetry). I do wonder how accurately this book represents Punch - the book's author is clearly critical of it and this blog's author, like most modern Americans, has never seen a full issue. Still, as far as I can tell this is the only book that covers this topic even in part.
By the way, most cartoons (which were originally full-page sized) are by John Tenniel of Alice in Wonderland fame. He didn't sign the earlier works but that little squiggle that looks somewhat like the Artist-Formerly-Known-As-Prince's icon is his signature.
