This volume catalogues the world’s most comprehensive collection of American portrait miniatures, ranging in date from the early 18th to the 20th century and representing 155 artists. Jewel-like and intimate, the pieces portray spouses, children, and other loved ones and were usually created for personal use. The Museum’s collection is also significant for its self-portraits by artists and for portraits of notable public figures. Each of the nearly six hundred works is illustrated and described in detail, and a biography and bibliography are provided for each artist. Two essays chart the history of the collection and the stylistic development of casework and lockets.
