When I first started researching this oddly named studio, I thought that the American Ping Pong Studios were in some way related to the 1920s craze for table tennis! Upon further investigation, I discovered that a Ping Pong Studio was a type of basic photographic studio, usually located at a tourist attraction, which offered inexpensive and quickly produced portraits. A 1909 book by J. B. Schriever entitled ‘Complete Self-Instructing Library Of Practical Photograph’ outlines how to set one up. Other references refer to a business model which charged more for fancy borders and frames than for the actual photographs.
The portrait itself is strong and I love her confident gaze at the camera. The beehive shaped toggles on her hat and the luxurious fur wrap are nice touches too.

I’d never heard of ping pong photos. Thanks for the link too, I’d never heard of that book either.
