This serene and atmospheric composition can be compared with another river landscape by De Vlieger in the collection of Jean Bonna, Geneva.¹ Both drawings are executed in pen and brown ink and wash, heightened with white, on blue paper, a combination of media that is relatively rare in the artist's work.  De Vlieger appears to have begun to use blue paper regularly only fairly late in his career, starting in the late 1640s.²
