Dutch Ship on Hand-painted Card by Keisui?
Well-executed painting of a Dutch vessel and tender, presumably at Nagasaki. Signed and stamped by the artist at lower left with a signature that appears to read Keisui （瓊水）but we cannot find any record of an artist with this name. Quite possibly a highly-skilled amateur artist whose work is unknown. Probably dating from the Bakumatsu Era (c1850s).
Painted on thick card measuring 27.1 x 24cm.
In good condition with some wear, minor marks and minor discoloration.
