On Sunday our dear friend Jack-- eminently knowledgable about the city’s history and architecture -- took me and Andrew on a private tour of housing in North Philadelphia. We drove through neighborhoods that had been redlined; past blocks that were completely abandoned; through streets with boarded up homes and empty lots. And we also meandered through areas of revival with people on their stoops, tending their gardens and walking home from church. I was struck by this door of an old abandoned house. It is remarkable that the delicate etched glass has managed to survive everything else around it.
