"This lithograph by Kollwitz is one of many self-portraits the artist created during her lifetime. She depicted herself more than 100 times from the age of 18 up until a couple of years before her death in 1945. This drawing was done in 1924 and serves as a record of the artist's expression and outlook at this particular time in her life." http://www.artistdaily.com/blogs/drawing/archive/2008/07/07/looking-at-drawings-quot-self-portrait-quot-by-kathe-kollwitz.aspx
