4) This is the most expensive piece in my collection in terms of what I had to do to get it. My sister received this paintable sculpture as a Christmas gift years and years ago. In order to keep it for myself when she moved out, I had to give her a pen and ink drawing of a falcon (that I really liked!) that took me nearly eighty hours to do. I really love my sister but boy, does she know how to shake a guy down or what?!
