Old ink and watercolor drawing of early 19th century men and a boy pictured in an English interior, executed probably early years of the 20th century, signed "O. Krause" and also bearing the word "Copy", 6 1/2" by 6" inside the opening in black glass eglomise style "mat", 10 1/4" by 9" as it was originally framed. The drawing seems to me to be after perhaps an original illustration in a Charles Dickens (or other English author of the period) book. Dickens works were illustrated by a number of artists in the 19th century, among them Hablot Browne ("Phiz") and George Cruikshank. This is all just a guess as to what relationship the drawing might have to a known drawing and artist. The work was in an inexpensive old strip frame which pretty much came apart during photography session. You could keep the eglomise with gold piping as a "mat" but a new frame might be a good idea.
