Scrambling around an eccentric uncle’s tall, skinny row house would be a treat for any kid — all the more so if your uncle were Andy Warhol, and the house, his art studio. James Warhola is just that nephew, and in a new book, called Uncle Andy’s Cats, Mr. Warhola writes of the fun he had visiting his Uncle Andy. Host Scott Simon speaks with Weekend Edition’s ambassador to the world of kiddie literature, Daniel Pinkwater, about a new book for children called Uncle Andy’s Cats.
