A little of Loretta Young (featured this month on TCM) goes a long way at the Daily Mirror HQ, but I noticed these shots of a department store in “Employees’ Entrance” and they reminded me of the sequence in “Public Enemy,” which was identified as being filmed at the May Co. These light fixtures certainly look familiar.
Hm. Is that an escalator in the middle-left?
There’s the escalator and there’s the May Co.’s clock!
Now was this the May Co. or a set? Time for more detective work.
