Stipple and etching, rare. 132 x 210mm (5¼ x 8¼"). Small tear top-left.
Margaret McAvoy (1800-1820), captioned in Robert Cooper's print of 1821 as 'An extraordinary Blind Girl'. In 1817 Liverpool physician Thomas Renwick published 'A narrative of the case of Miss Margaret McAvoy'. McAvoy was reputed to possess extraordinary powers of recognition through touch and smell, and to silence his critics Renwick carried out a series of experimental tests on the girl, involving various masks and blindfolds (as shown here). Renwick's account also reports McAvoy's ability to distinguish different colours of fabric and paint, as stated on this print. It is probably derived from the frontispiece to Renwick's book.
