While organizing the paperback chapter books in their own bookcase at home the other week, I was looking at the cover art. I found five novels by well-known writers whose the publishers commissioned cover illustrations by the best illustrators, whose children’s books have won multiple Caldecotts, Caldecott Honors, many other awards too numerous to record here. 
1. Chris van Allsburg
2. Paul Zelinsky
3. Trina Shart Hyman.
4. Brian Selznick
5. Edward Gorey (the only major cover designer of the five)
This was a fun post but my favorite covers for the Chronicle of Narnia were created by Caldecott winners Leo & Diane Dillon. They received the Caldecott twice and were also what I would call “major cover designers”.
Your point taken. It was, like many of the pandemic posts, written with what was on hand at home.
