Museum of Fine Arts

In fairness, such a high-traffic, low-status space is appropriate for these works. Posters aren’t made as subjects of study. They put a premium on attractiveness and accessibility (though usually accessibility with a twist), since posters are intended to be seen on the fly — by passersby, not connoisseurs. They’re images taken in almost unconsciously rather than scrutinized and pondered. So the 41 examples that make up “Art in the Street” fit right in amid all the pedestrian hubbub.
