If you're standing on Broadway between 62nd and 63rd Streets and just need to know what that same spot your standing in looked like during that scene from Taxi Driver, then as with anything these days you need look no further than your phone.
The Scenepast iPhone app will transport you back momentarily with a program that allows users to search for a city and year, see a photo from favorite old movie scene shot in the area, and then compare it to how the spot looks today. The app works for both movies and television shows... but hopefully similar ones will come out to focus on album art, and just Older Times.
