Subseries 1: Correspondence, 1928-1937, undated

The bulk of Morgan's correspondence is with his co-author, Mantle Fielding, documenting the research, writing, publication and distribution of The Life Portraits of George Washington and Their Replicas. Correspondence is with private owners, galleries and museums regarding the gathering of information on provenance, attribution, condition, and current ownership, as well as the acquisition of photographs. Many of the letters are outgoing only. Post-publication correspondence concerns sales and storage of the volumes, as well as new information on Washington portraits. Additional correspondence with Mantle Fielding can be found throughout the collection. Correspondents include Francis R. Appleton, Jr., Theodore Bolton, and Walter Jennings.
