H. Werner Zimmermann was born in Austria but grew up in southern Ontario, Canada. He writes and illustrates his own picture books, and also illustrates books for other authors.
I recommend this book as a teaching tool for basic shapes introduction to build on from about 2 1/2 and up. Also, it's a fun read for Valentine's Day, as well as a conversation starter for caring about and loving others, and what you might choose to do for someone you care about. All the Alphonse knows books are enjoyable and educational.
