The artist is probably Ernest Delannoy (d. 1869/1872), who accompanied Whistler on the Rhineland trip, although it could be a self-portrait.
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.
