The 2014 version of The Fish with the Deep-Sea Smile really shows the difference illustration makes in a picture book.
This was written by Margaret Wise Brown, offer of the famous Goodnight Moon. It was first published in 1938, with illustrations by Roberta Rauch. (You can see the cover below.)

I just read the 2014 reissue, illustrated by Henry Fisher. (See cover below.)

While the earlier illustrations look old-fashioned, the new look too light and colorful; they distract, and diminish from the impact of the book’s verse.
I also found the black type on the dark blue of the sea hard to read at times. Though the images were pleasing in themselves, there was a lack of fit between them, the design, and the text.
