Four panoramic group photographs taken at annual conventions of the Pacific International Photographers Association. Carl Knight is pictured in all four. Also includes Paul Christopher's notes on these photographs, written in 2018.

The collection consists mainly of photographs, negatives, and slides of portraits and scenic views of Missouri and Southern California. In addition to the images, there are a few textual items including financial documents, newspaper clippings, miscellaneous ticket stubs and pamphlets that Knight collected, and correspondence (mostly postcards) to or from Carl Knight's sister, Pansy M. Knight.
