They don't let you bring anything other than dry media into the gallery, so my trusty pens and watercolors stayed home and I had to struggle along with some colored pencils.
It was pretty crowded, and the drawings were very small, but with patience I was eventually able to work myself up close enough to see to work without blocking other people's view. At least I think I wasn't. Nobody kicked me anyway... I've read that when you are copying a master's work, you are trying to channel a tiny bit of their spirit. I don't know about that, but if Michelangelo was looking over my shoulder at all he was probably just ticked off that his workers hadn't burned these sketches like he told them to.
If you do a drawing of a sculpture, is it still called a copy?
One of my favorite pieces in the regular collection, by Robert Henri. I wish they would let us bring our oil paints in, so someone could do these works justice.
