The Seabury C. and Agnes W. Mastick Papers consist of materials that primarily document the relationship between the Masticks and Oberlin College. The materials document the Mastick's donation to Oberlin College in 1961 for the construction of the Warner Concert Hall, and their honorary degrees awarded by Oberlin College in 1962. The philanthropic activity of the Warner and Mastick families are documented in this collection.

The collection contains some biographical information, including Seabury Mastick's honorary degree received in 1916 from Oberlin College, and a certificate for membership in an honorary society in 1891. Oberlin College publications, news releases, and newspaper clippings provide information concerning Mr. and Mrs. Lucien Warner, the parents of Agnes Mastick, and their donation for the construction of the first Warner Hall. These materials also provide information concerning the Masticks and their donation for the construction of Warner Concert Hall in 1963.

The correspondence series primarily contains thank you letters to the Masticks from Oberlin College administrators (i.e., President) and alumni for the donation to build the new concert hall. Other letters concern the transfer of property from the Masticks to Oberlin College, and their honorary degree received in 1962.

Eight photographs (originals and copies) depict Mr. and Mrs. Mastick in their later years at their home in Florida. One photo is of the high school class in Lake Chabot, LA, in June 1887.

The collection is divided into three series: Series I. Biographical, 1891, 1916, 1962, 1964, n.d.; Series II. Correspondence, 1903, 1953, 1957-1965, 1970; and Series III. Photographs, 1887, n.d.
