Dad and his big family are back--and this time they're visiting the museum! Every Sunday morning, Dad prepares ten croissants, ten mugs of hot chocolate, and ten glasses of orange juice. Then, everyone hops on his bike and they all go to look at paintings by the Great Masters. Only there, in front of his favorite painting, would he finally relax. But, one day, after being lost in thought, he turns around to discover that all ten children have disappeared! Where could they be? A fun follow-up to The Dad with 10 Children.
