At the beginning of this subseries is a disbound record book maintained by the gallery to record purchases of early American miniatures. The book contains photographs of each miniature, arranged alphabetically by artist, and includes notations on the portrait subject, and from whom and when it was purchased.

The subseries also contains a group of scrapbooks of photographs of works sold by the gallery, and stating the date of sale and buyer. Each scrapbook has an index, arranged alphabetically by artist, of the photographs included. Books 1 to 4 and 16 to 18 are complete while books 5 to 15 have had the majority of the images removed. Scrapbook 9 is completely empty except for the index and Scrapbook 7 is missing.

The rest of the series is comprised of photographs of artwork, many of which were removed from the scrapbooks described above. These photographs are arranged alphabetically by artist. The majority of the photos are undated; however, those that come from the scrapbooks in the collection are arranged at the back of the folders chronologically by date of sale in order to link them to the scrapbook indices.

The artist most heavily represented in the photograph files is Winslow Homer. The gallery evidently maintained separate scrapbooks recording sales of Homer's work (labeled here for clarity as Scrapbooks One to Four) and these can be found here in addition to four folders containing photographs of Homer's work and related records. The first of these four folders contains miscellaneous photographs from scrapbooks. Those with dates of sale linking them to the scrapbooks in the collection are in chronological order in the back of the folder. The second folder contains photographs of works that are of questionable origin or are merely attributed to Homer. The third folder contains unidentified or unlabeled works by Homer. The fourth folder contains miscellaneous information on Homer exhibits and gallery collections of his work including photographs and lists of his work owned by galleries and museums.

The Homer Book One contains loose scrapbook pages with attached photographs of artwork which are arranged alphabetically by title; Homer Book Two is a scrapbook of photographs of watercolors only, arranged alphabetically by title. The pages also include details about ownership and sales of the works. Some of the photographs are missing.

Box 14 contains loose pages from a third scrapbook of photographs of oil paintings in the same alphabetical arrangement as Book Two. Book Four contains loose scrapbook pages with attached photographs of drawings by Homer, again arranged alphabetically by title.
