Dealers, Galleries, Restorers, and Museums

The arrangement of the second series reflects the arrangement and titles created by the original processors, although some folders have been relocated to the other five series. Folders are organized alphabetically by last name. Folders relating to Martin Birnbaum are further subdivided between content sent by Birnbaum to Winthrop, and all other content pertaining to Birnbaum.

Many of the names listed on the folder titles are art dealers who worked with Winthrop throughout his art collecting career. Some of the other titles, however, refer to art critics and historians that Winthrop corresponded with. Where possible, the processor noted what type of artwork each dealer dealt with and included this information in brackets on the folders.

Although the contents vary depending on the individual or organization that they relate to, many of the papers includes letters written to Winthrop that describe the discovery and the pecuniary, intellectual, and aesthetic worth of various pieces of art. There are also many monetary records pertaining to the work that Winthrop purchased such as checks and invoices. All of the documents are located within archival folders housed in file-sized folders.
