Possibly drawn in Cologne in Germany, where Whistler and his companion waited for a money draft to see them through their return journey.
Unknown. It could have been the daughter of the landlord, Herr Schmitz, who had a personal interest in whether Whistler received some money to pay for his board and lodging, to which end he visited the post office daily.
The sheet was probably taken from a sketchbook. Over fifty drawings, many in sketchbooks, most of which dated from 1857-1858, were apparently given to Whistler's half-sister Deborah and/or her husband, Francis Seymour Haden, and were later removed from the sketchbooks.
See further details in r.: Les Côtes à Dieppe; v.: Cliffs and building m0222.
It was not, as far as is known, exhibited in Whistler's lifetime.
Due to the conditions of Freer's will, it cannot be lent to another venue.
