Oh, man. I went to the Picasso museum the last time I was in Paris and I was lucky because the day after I went, the museum closed down for renovations until 2012! I had no idea it was closing, but just showed up and had good timing. I also had no idea that Pablo Picasso had designed costumes and masks for a Commedia production.
Below are photos of his Pulcinella sketch and mask. Look closely at the mask. It's made of wood and canvas, and totally nontraditional. I love it (sort of)!
