Henry B. Bounetheau's Aunt by Edward Greene Malbone, ca. 1804, Smithsonian American Art Museum. One of my favorite miniature portraits in the collection of over 400. Miniature portraits of watercolor painted on ivory were popular before the advent of photography. The size is about 3 x 4 inches. The details of the sitter's skin tone, hair style, clothes, and gaze are exquisite.
