Ad Reinhardt wanted to create artwork “about which no questions can be asked”—images that represent only themselves. But we're pretty sure we can spot a cigarette in this untitled work, and pacman eating a mountain. Reinhardt’s early work feels like an extension of cubism and the abstraction of early modernism. Later, his work became minimal and severe, less like looking for shapes in the clouds and more like staring into a starless night sky.
