I made a series of 14 cross section drawings for the construction of the bison model and final life-sized bison sculpture. For my solo show, I blew up the tallest, widest cross section drawing using an overhead projector. I even transfered my disorderly notes to myself and my scratchy 5th-grade-boy handwriting. I used this gigantic piece of graphite to draw the whole thing. It gave the feel of a single (albeit gigantic) pencil line.
Here it is at my show. The actual cross section is now 76" tall, which is the height of the bison sculpture at it's highest point.
