The handling of the landscape is comparable to that of a drawing from Holkham Hall, sold at Christie's, London, 2 July 1991, lot 38, illustrated, and to another in the Art Gallery of Ontario, Toronto, M. Cazort and C. Johnston, Bolognese Drawings in North American Collections, 1500-1800, exhib. cat., National Gallery of Canada, Ottawa, 1982, no. 63 recto, illustrated.
The figures are close in type to those published by Isabella Lodi-Fè, Un Disegno di Giovan Francesco Grimaldi, Nuove ricerche in margine alla mostra da Leonardo a Rembrandt, Turin, 1990, figs. 3-5.
