The boy at the keyboard in this pen-and-ink drawing is presumed to be the young Mozart.
The work has long been attributed to the German-British painter Johan Zoffany (1733-1810). Recent research, however, rules him out and the authorship is presently unknown. In private hands for two centuries, the drawing has been acquired by the Salzburg Mozarteum Foundation at an auction in the Librairie Henri Godts in Brussels. It goes on display this week at the Mozart Resident in Salzburg until the end of October.
