This is an autographed copy of Jimmy Fallon's new children's book, Your Baby's First Word Will Be Dada.  This cute book is a series of pictures in which daddy animals try desperately (and utterly fail) to get their babies to say "dada" as their first word.

This best-selling book by the host of The Tonight Show was published in June 2015.  It comes with a certificate of authenticity for the signature.
