This is a picture I did not take
of a fashionable young woman in sunglasses, standing three feet away from Jackson Pollock's "(One) Number 31, 1950" at the MoMA in New York, while moving slowly left to right, in and out, as she took single-frame stop-motion shots of the painting with her Super 8 movie camera, just as I was bumped from behind by a German tourist wielding a Nikon and wearing a green felt hat, while I generally ducked everyone else's camera angles, thirty-minutes before closing time on a holiday weekend in a museum that allows photography on all floors but the sixth.
If no one can take pictures on the sixth floor, does the sixth floor still exist?
