An organ grinder (with a stuffed toy monkey banging little cymbals). Check out the large picture of the organ itself so you can see the beautiful inlay work on the audience-facing side.
Banjoist (dreamy ... sigh ...).
Nickel-harpist. I've never seen one of these instruments before. I did a double-take once I realized what she was doing. Basically a violin with keyed fingering on the strings for different notes and chords.
