I saw some film footage at the Academy (AMPAS) one time of Clara Bow, along
with Rex Bell, being interviewed in a booth, like the one above, at the "It Cafe"
and signing autographs for some fans as well.
***I looked up the program. What I saw was titled:
Newsreel: Hearst Metronome -- "Clara Bow Opens Her 'It' Club in Hollywood" (9/13/37)
