Can You Name This Children's Book? (episode 2)

If this image immediately makes you think of a particular fall children's book - join the club!  It's one of my go-to books each year.  Need another clue?

"But if you want to visit my tree, come in the fall.  That's my favorite time.  Can you guess why?"

It's Red Leaf, Yellow Leaf, by Lois Ehlert.  I love it - do you?
