Art museums have a reputation for being unwelcoming. Often their grandiose architecture looms with self-importance over their surrounding neighborhoods. Think about it. Just setting foot in the Philadelphia Art Museum requires that you climb a set of stairs so imposing that it has been immortalized as a professional athlete’s workout. (Are you singing the Rocky theme song yet?) And the mental workout? Sometimes you can feel like a poser if you don’t have an advanced degree in art history. I know. I have a minor in art history, and there are times when I feel daunted by a mere exhibition leaflet.
