We're constantly amazed by the stuff that comes in on Gothamist Contribute. For instance, yesterday Allan Mohlo sent in a single black and white picture of a Richard Hambleton shadow-figure. Hambleton is a well-known streetartist from the 1980s, but we've seen relatively few photos of his pieces, so this one piqued our interest. We clicked through to Allan's Flickr stream, and lo-and-behold, found this amazing set of streetart shots. Check out a few of them:

Bonus: check out Allan's other sets-- he has some great Diana pix from the same period. If you've got some old NYC pix, send them in-- we love seeing this stuff.
