A Philadelphia section has just been added to the main archive (HERE), with photos primarily taken along the Market-Frankford SEPTA line in West Philadelphia. The area is predominantly residential, though the population has dwindled in recent years. There are small commercial clusters around the El stops, but lots are mostly vacant and storefronts boarded up and decaying. Work from public art initiatives like the incredible Mural Arts Program pop up all over the city and brighten blighted areas and transform public space. Here’s a quick preview: Here’s an interesting interactive city map that gives a larger view of the vacancies in Philadelphia’s neighborhoods (link).
