Many Barberiana collectors are aware of the old (very old) Barber Shops of the past. You may also be aware of the wall clocks that were on their wall opposite of the mirrors in these wonderful establishments.
When the barber would turn you around while you were sitting in the chair, all you had to do was look in the mirror, the clock face will display accurate time when you look at it via a mirror.
The face is in reverse and when viewed in the mirror it looks normal. If you look at the clock straight on without using the mirror, it is just a very confusing mess.
I would assume that only the very busy or large Barber-shops would have these. But they did exist.
Very rare. I have been looking for many years to find an original one. I think I will see peace on Earth before I find one.
Yes, they pop up on auction sites on occasion, but not original.
The two pictures posted below are from the web and are not original, but it will give you the proper visual description of my post.
If you have a small hand mirror, double click on one of the below pictures to enlarge it, turn away from your computer, hold the mirror up and view your monitor through the mirror, and there you have it.
I make clocks occasionally in my garage wood-shop, normally I give them away as gifts. I do not make the clock movements of course, just the housing that holds the clock movements.
Below is a couple of my creations. I use one as my "Avatar"
As I was online ordering some supplies from one of my Clock Parts suppliers, I ran into their new product page.

It's always important to know what you don't know.
