Have a look at the Underground New York Public Library, a project from the photographer Ourit Ben-Haim, collecting images of the NYC Reading Riders.
A side remark, since then I started noticing how few people are actually reading books in public around here, at bus stops, airport lounges, ferries or in the Jærbanen. Mostly reading magazines and being busy with their phones. Quite a striking difference when I remember my commutes in and out of Paris.
Maybe the commutes are too short here. Or they have time to read at home.
Yes, it's an excuse, I haven't made any half-decent drawing in ages.
