If I picked up what purported to be a serious book on the history of the Vietnam war and I opened it and it had cartoons in it I would think the book was not serious and certainly not buy it as a result.
As someone who reads a lot of non-fiction books, yes there are photos and maps and illustrations in them. What they don’t have are cartoons for goodness’ sake.
If you want to read cartoons for adults then there are enormous numbers of graphic novels, manga, and other such books available. My local bookshop has an entire section dedicated simply to those.
