Apparently a preliminary study for the etching of 1616 in the same direction, though of different sizes, see the following lot. A comparable drawing in the same technique attributed to Jan Breughel I, also on vellum but of larger format, signed, dated and inscribed 'Joan breugel.1616.den.10 ocktober. In neurenberg' and 'St. Jops Kerck', is in the Rijksprentenkabinet, Amsterdam (inv. no. 1908).
