Wood sculpture. (2 prints)., undated

Most of these photographs undoubtedly were printed from the negatives made by David Rosen. His New York logo is embossed on many of the prints. Unfortunately, unlike the negatives, which are all numbered so to correspond with the index cards, these prints are not identified as such. Therefore, the photographic technique employed is not always clear. Occasionally, however, an "I-R" is written on the backs of some of the mounted prints, probably indicating that the image was made with infrared photography. The prints offer a visual survey primarily of European art of the 15th to 19th century. For most of the artists, several of their works are documented, often with multiple images of each painting. Images depict various surface and substructure details, from an artist's signature to evidence of underpainting or canvas repair. Many panel paintings are examined and include images of cradles, a support once used to counter warping and shrinkage. Additional photographs supplied by other sources are also included.

Almost 38 prints, previously filed by various artists and titles, were transferred to the "Subjects" series as a "Writings" folder. With captions attached to the verso of each, these prints served as most of the figure illustrations to an article by Marceau, reprinted in the December 1953 Proceedings of the American Philosophical Society. Prints of other works of art remaining in this subseries also have captions or some type of didactic text attached. The intended use of these prints, however, could not be determined.
