As mentioned in my Back from Chicago post previously, below is the postcard of the Barber Shop in the Blackstone that I thought was lost forever in the mail. Below it is a picture of the Barber Shop that I took when I got to go inside (they keep it locked usually, but we saw it on our tour).
You can see the fountain on the back wall with the clock above it is exactly the same, the light fixtures, etc. You can even see me in my bright orange jacket taking a picture of the room if you look close enough in the mirror. :p The rust circles on the floor in the photo are from where the barber chairs were. However, there are only six rust circles on the floor, and eight chairs shown in the postcard.
