Another from The Kepes/Lynch Photograph Collection and one of my favorites. Would Mondrian have liked this image? Not enough boogie-woogie for Piet, perhaps, but a fascinating play of placement, right angles, and parallelisms, regardless. This is neither painterly space nor warm pictorialism, but a chilly graphic consideration on ground glass, something that must've looked, upside down, like some kind of perfection. The shadows aslant the stairs say it's after Noon. The photographer noted time of exposure as 2:00 PM, April 19, 1957. The clock in the window says 1:50.
