Historical building/landscape images of all kinds are uploaded to the Sepiatown website and placed on google maps as accurately as possible, creating something of a time travel effect, once you get immersed in it.
The main page is in Manhattan, but you can enter any location on the map field to see images elsewhere.
I've uploaded several images of the Hudson area, and hope to continue gather and post as many more as I can get access to.
In cases where Google Streetview is available, you can click on a "now/then" link next to a picture to see the same view as it appears (roughly) today.
For instance, here is a screenshot of the website with the antique South Bay postcard I uploaded, shown alongside the Google Streetview of today.
Sepiatown can be a bit of a roller coaster ride, as you have to witness all the beautiful things that have been destroyed, but get to see all the beautiful things that have been preserved, too.
Unfortunately, in Hudson, Warren Street has not been photographed for Google Streetview, only Route 9G has---so, the now-then comparisions are limited to South 3rd and, yay, Columbia Streets.
Sure do wish I had a 100-year old sepia photograph of this place!
