The Macbeth Gallery records provide almost complete coverage of the gallery's operations from its inception in 1892 to its closing in 1953. Through extensive correspondence files, financial and inventory records, printed material, scrapbooks, reference and research material, and photographs of artists and works of art, the records document all aspects of the gallery's activities, charting William Macbeth's initial intention to lease his store "for the permanent exhibition and sale of American pictures" through over sixty years of success as a major New York firm devoted to American art. The collection measures 131.6 linear feet and dates from 1838 to 1968 with the bulk of the material dating from 1892 to 1953.
