Philadelphia Bourse Building by emilienoelle
The Philadelphia Bourse Building is located on the left hand side of Independence Mall when you are facing Independence Hall. It is a gorgeous old brownstone, often with a trolley tour car parked in front. This is a good place to know about not only if you want to take a trolley tour, but because inside of the building there is a large food court and several small shops that sell things like cold drinks and film. (There is no indication of this on the outside of the building.) Also, the Mexican Consulate is located in this building, in case you're Mexican and need to go there. (And I know this because I read the sign, not because I was following around a bunch of Mexican guys. Don't be smart.)
