Many children dream of taking spaceships to the moon. The Vitra’s new Black Box—a dark space designed for deep reverie—is showcasing vintage robots and astronaut figures that date from 1937 to 1968. These futuristic toys were collected by Vitra’s chairman emeritus Rolf Fehlbaum. For kids: imaginative flight. For nostalgic parents: transport into the past. —C.J.F.
