At the Minneapolis Institute of Art are a small number of plaster casts dating back to the days when the museum first opened. I was delighted when I found out that a full-sized cast of Michelangelo's "Pitti Tondo" was among the casts in an area not normally open to the public. The guard who told me about the tondo helped secure access for a short time so I could photograph it to model it later.

So here is my model of Michelangelo's "Pitti Tondo" based on a plaster cast.
