It's an interesting concept, but I am skeptical about a small child having the ability to think abstractly and A. realize it's a face on the book and B. connect that to themselves, since presumably the aim of the book is to send the reader to sleep.
Verdict: Quirky, possibly a little too quirky. I'm trying to get my board book circulation up so I'm not getting any iffy purchases right now, just good, solid popular titles. If you're looking to expand your horizons a little though, this would be an interesting addition.
