…both marble and plaster busts, of course. The Royal Academy of Arts has a nice feature – a room where they’ve busted out (ha) (sorry) their old …busts, and made them into a pleasure/education feature by adding benches and free paper and pencils. You can sketch the busts and practice drawing. Or if you’re me, you sketch a few busts, and a few sketchers.
The mauve Uni-Ball is a very unforgiving pen for sketching, especially moving tragets like the bearded art lover. But the HB pencils provided by the museum were even less satisfying when I used them for the readers on the bench.

These guys stood still for their portraits… very still.
