The link is to a zoomable version on the Google Art Project; there is a downloadable file on Wikipedia; the original is in the Smithsonian American Art Museum, which also has a zoomable version.

As his father, Charles Wilson Peale, had done for him, Rembrandt Peale tutored his daughters in painting and the sciences.

Here, his affectionate portrait of Rosalba in her early twenties shows an alert, pensive young woman sitting for her portrait with patient equanimity.

Rembrandt Peale also painted a later portrait of Rosalba with her sister, Eleanor.
