From 1 to 40, from dance partner to handyman, the fun and functions of grandfathers are inventively enumerated. The book's charm is in how the "use" term and accompanying illustration pair up. Sometimes it's straightforward, like the arms-circled-out-in-front "ball hoop." Other entries, such as grandpas' "uses" as entertainment centers, butlers, and mediators, supply kids with a fresh perspective on all that their grandparents are and do for them. Note that while kids and grandparents are rendered with realism and obvious affection, this book avoids stock shiny-happy-perfect depictions. Number 2, showing grandpa's pained look at having to serve as a turtle veterinarian, is an apt illustration of this. At the end of the list, it all adds up to grandpa being a wonderful friend.
