Forgotten New York City

Forgotten NY, "the infrastructure of a lost metropolis," is a trove of wonderful old New York City-related photos and details. With topics such as, "Old Advertising" (which is always one of my favorite things to see on the side of a building), "Streetlamps," "Cobblestones," and "You'd Never Believe You're in NYC," it's enough to keep me poking around for a long time. Very cool! [via Gawker]
