A friend of mine shared this Facebook page with me a couple of days ago, and I thought some urban folks might be interested. The contrast between then and now is incredible. There are about 450 photos in the timeline album. It's also interesting to read comments from other Facebook users. Clearly, a lot of old New Yorkers follow the page, and some of them talk about living in the places shown in the photos back in the '70s. Dirty Old 1970s New York City 13th and C Orchard St. in Soho 5th St., between C and D Lower East Side St. Marks Place, between 2nd and 3rd Avenues 6th Avenue and 49th St. 3rd St., between 2nd and 3rd Ave.
