If ever an old postcard was suitable for framing, this one would head the list.  As great as it is on the front, it turns out to be an unused ad card for something called “Ess Tee Dee (STD) Stops the Dandruff” from a Chicago company, for a product to be used in barber shops.  Similar cards that we found online (we couldn’t resist) describe this as a scalp food.  Grade: 1
