Subseries C consists of side-transparencies. The slide-transparencies subseries C are distinct from the loose and eclectically gathered slide-transparencies in "Series 3 subseries B photographs and slides". The slide-transparencies that have been cataloged in Subseries C are labeled by project and have been placed in slide containment boxes or carousel wheels in a meticulous order by Harold Spence-Sales.
The images in the slide-transparencies are primarily of aerial photographs and geographical areas.
