These are the Grzeszczak boys—Lukas (holding Duck Duck), 4, and Owen, 2—on board this little train car right out of Donkey Hodie’s world on display at the Elmhurst Art Museum for the current exhibition, Designing Donkey Hodie—From Make-Believe to Someplace Else. Lukas’ and Owen’s grandparents brought them to the puppet demo and workshop on Saturday, July 20. The exhibition remains through Sunday, Aug. 11. More photos inside.
