Just trying to figure out this perspective below (click to enlarge).
Is that looking down Liberty, the intersection above at center left? Help old Pittsburghers! Bonus points to anyone who can identify who's on the billboard at right.
Image assembled from FDR visit to Pittsburgh footage (1940). Just before this, the camera pans east to west away from Union Station as FDR's train departs (look closely and you can see him waiving from the caboose).
