This looks to be very good. From the press release:

Postcards as we know them today didn't come into being until 1907. This new postal service development neatly collided with the invention of the first affordable and portable amateur camera. In a brilliant feat of marketing, Kodak created a service called Real Photo Postcards that allowed a person to make a postcard out of any photograph they took and send it for just a penny. This craze took off and was popular throughout the early 1900's. Real Photo Postcards is a collection of the most outlandish and idiosyncratic, beautiful and even occasionally bizarre images of this early postcard period.

Assembled from the collection of Harvey Tulcensky, and edited by corofriend Laetitia Wolff, this would make a nice holiday surprise
