Just to confirm that Pictures 2 is definitely Norman Lewis - the photo is, as someone suggested, in Julian Evans' biography of Lewis, Semi-Invisible Man.
Another tentative suggestion for Madhouses 2: the American poet Hart Crane wrote a long poem called The Bridge, made up of several named sections. One of these is 'The Tunnel', which is based in the New York subway. Although it's not explicitly a 'madhouse', its inhabitants (including the ghost of Edgar Allan Poe) are pretty off the wall and he paints a bleak, Stygian view of 'life' below ground.
Here's the Url for the poem if anyone is inspired!
