The Triple Portrait:

This one was unusual in that I had to draw it on a special 11 x 17" card stock as at the time I didn't have any large sized paper.  Now that I am doing this work again I have paper in  9x12", 14x22" and 14x17" sizes to work with. 

I did this one from three photos.  One of the man as a child, one as a young man and one as he is today.  This piece took about five and a half hours to complete.
