The following is the caption by Elizabeth McCausland accompanying the original 1939 edition of Berenice Abbott's Changing New York publication.

Unaltered, except for an occasional coat of paint, from the day it was opened to the public 60 years ago, is the typical 'El' station interior. The turnstile is a fairly recent innovation, having come into use as lately at 1923. Noisy and awkward to handle, it seems as antiquated as the architectural layout and heating apparatus.
