Focus on this artwork and discuss the Design.
The interior lines in the drawing make up a bird with head and beak both facing right, and the tail to the left. The feet are below, and above the bird's wings are spread. The overall design is made through a process of concrete engraving. First a wooden frame was constructed and filled with dark rock materials and then covered with concrete. The surface of the concrete was then sandblasted following a template and the blasted away material revealed the dark material in the lines on the surface. Picasso was introduced to the process by Norwegian artist Carl Nesjar.
