This first is an example of my least favorite kind of art, published in 1968. Brings back memories of Yellow Submarine, and all those horrible cartoons like The Three Stooges.
This second example is from the mid 1970s, and is a much more easily embraced style of drawing.
I picked the above illustrations for a reason. One of them shows a tiny bit more attention to detail, or was thought out a bit more in advance. It’s hard to say what exactly happened, but one of the artists forgot that to have so many hats in the air meant people needed to actually take off their hats.
We love that book, though. The below illustration makes me smile every time I look at it. I feel exactly like that little girl feels when she looks at the math problem on that blackboard.
