This piece is called "Christ and the Virgin with Music-Making Angels" (1789-1869). The German artist Johann Friedrich Overbeck drew this piece with graphite on wove paper. To me, this piece looks like it was drawn with a led pencil on a piece of paper. In this picture the artist has Mary and Jesus in the center of triangle and the angels at the bottom corners of the triangle. The sketch lines are curved and clean, and looks like it has no mistakes. The space in triangle, being taken up by Mary, Jesus and the Angels is filled up and overlaps the triangle's bottom angles. There is unity in this piece, It looks like a family enjoying each others company, playing music and singing songs. Mary, Jesus and the Angels seem to be having a wonderful time.
