This New York Times article starts out with a neat draggable image that overlays two images of Grand Central Terminal over each other — one from 2008 and the other from 1978.
The article goes into how Grand Central has more or less remained ad-free in the past 30 years while other public spaces in the city have gone on to be covered top-to-bottom in advertising.
Anyway, go over to the article and drag the slider around to compare the images of the terminal.
