Just this week I stumbled a rather well-loved copy of his counting book Teeth, Tails, & Tentacles in the library at my daughter's preschool. One of my favorite things about this book was the use of unexpected vocabulary. For example, for the number 15, Wormell features fifteen leopard rosettes. I've never before encountered the use of that term to describe the large, two-toned spots on a cat, but it's lovely and fitting. So often books for the very young avoid using big words, which is a shame, since how else are children to learn such words if they aren't exposed to them in a memorable context?
Wormell's bold linocuts are definitely memorable. I encourage readers to peruse the entire collection of his illustrated children's books on his website, here.
