Before the age of photocopies or even carbon paper, Audubon replicated his voluminous correspondence. On this sheet the artist copied his letter to William L. Curtis (ca. 1798–1870), described in documents as a “master mariner,” who lived in Eastport, Maine. Audubon was in contact with him during the planning phase for his Labrador Expedition (June 8–August 31, 1833) on board the Ripley. This letter is included out of chronological sequence in Part I of The Complete Flock because it is a recent acquisition, which is being exhibited for the first time.
