I was wandering through Shorpy just now (an excellent way to burn through a few hours!) and I stumbled across this image. I've never seen a period photo of this model shaving machine in an office. (Clues in this image suggest it's August 1922.) Interestingly, the recording machine is a Dictaphone, so apparently this office had no brand loyalty!
