Series IV: Photography contains source photography for artworks, negative film, glass slides, contact sheets, artist test proofs, slides of artwork, and framed photographs of friends and family. Slides of artwork exist both in 8.5 x 11" photo sleeves, and in three archival slide box systems assumed to have been arranged by Blanchon. The slides in the slide boxes generally duplicate the slides that have been arranged into sleeves; access to the slide boxes is by approval only, and researchers should use the sleeved slides for viewing.
One group of photographs has been processed within Series VII: Objects - see Object ID: 220.2.0055 "Box of family photographs".
