1922 - Isn't It Funny?

I recently obtained a PDF copy of the 1922 Palmer School of Chiropractic's supply catalog and it is a wealth of interesting things for the history buff! I found a bunch of stuff in there that is in my own collection, which I will be photographing and sharing soon. For now, here is something neat from the back cover (click on the picture to make it bigger!). I especially love the last line, which reads, "If your business isn't good enough to advertise, advertise it for sale." LOL
