This app accesses some of the hundreds of street vendor film rolls from the collection of the Visual Studies Workshop, Rochester, NY. Andy Eskind digitized the rolls and makes them available through his website @ http://andreweskind.com. The site also has a wealth of information on the history of the Joseph Selle Street Vendor Photography practice.
The Selle Scroll app is developed by Chris Burnett, a member of the Selle Circle with Andy, Mary Panzer, Elisabeth Tonnard, and Dave Mount. Special thanks to Elisabeth and Joachim Schmid for great feedback during development.
