Adam had a post regarding the Boston neighborhood markers (http://www.universalhub.com/2012/what-happened-mar...) and I had mentioned about the old street signs that still exist in Boston, such as the one on the corner of Temple and Baker Street that still exists.
Over the past few months, however, I have been using Google Maps and Bing Maps to find pictures of the signs that still exist. They are divided into sections; simply click a point on the map, and select Street View to see the image.

One of these days, I will try to get clearer pictures than what Google has, especially the ones that were taken in 2007 that look grainy.
Feel free to take a look and comment (nicely, of course). Thanks!
