I think I posted it back in February, but I was chuckling again at this barbershop ad found in the 1936 30th anniversary journal of the Kiever Revolutionary Branch 25 of the Arbeter Ring (!), a Jewish mutual aid society based in New York. "Haircuts and Finger Waving" teehee.
I couldn't find a direct photo of the barbershop but we can see the corner of it from the photo of the next building over, from the 1940 WPA tax photo.
