Perusing those bins of vintage postcards at flea markets is always a treat, but who wants to mail and part ways with such fun pieces of nostalgia?

If that wasn't enough, ScenePast also has a feature that provides the current-day view of the streetscape depicted on the postcard--a fun tool that is sure to prove addictive for history buffs.
