To know what a maverick artist looks like, look no further than Ranbir Kaleka. He wears a hat even when indoors, from which on occasion I have seen fish hooks dangling — or perhaps they were earrings. Unlike the networking artist, his eyes don’t dart impatiently across the room, scanning to see whether there are buyers interested in seeking him out. You have all his attention when he speaks to you, and his speech is deliberate, slow and accented.
