This portrait may have been painted to celebrate the 50th birthday of Thomas Gainsborough’s wife, Margaret. He portrayed her on various occasions throughout their marriage and her direct gaze — an unusual feature in portraits at the time — reveals the intimate bond between painter and sitter. This portrait might have equally been made to advertise Gainsborough’s talents as a portrait painter. Potential clients coming to his studio (and home) could easily compare the portrait with its model.
