I have posted a drawing at my web site by American artist/illustrator
Charles Dana Gibson.  The drawing depicts two buskers with a barrel
piano in London in 1897.

Gibson is best known for his "Gibson Girl" drawings although his
artwork covered a variety of subjects.  He was a keen observer of human
nature and society which helped to make him one of the most popular
illustrators of his day.

The URL of the drawing is:
