The present lot would seem to be comparable to a watercolour of the same subject, simular size by the same hand, signed and dated 1830, sold in these rooms on 20 november 1989. Another comparable watercolour, dated 1830, is in the Van Eeghen collection De Verzameling Van Eeghen, Amsterdamse Tekeningen 1600-1950 (B. Bakker, E. Fleurbaay, A.W. Gerlagh), Amsterdam 1988, no. 444 (illus.)
