Last fall, right after posting a 1958 press photo of a temporary fire escape stair set up in MoMA's Sculpture Garden, I went to the Corcoran in DC.
And look at that, they have a nearly identical fire escape tucked right in back there, by the vacant lot that once held their future. I suspect this is the staircase Sanity used when she fled the Corcoran board room several years ago.
