I'm planning an extensive research project to document graffiti in Philadelphia from the 1960s to current. I'm told Temple has a pretty good urban photo archive (including donated Bulletin files). I've seen what the Inquirer/Daily News has.

What other resources are out there?

I'm also wondering if there are some folks here or people you know who were city photographers in the 1960s and 1970s who may have incidentally captured graffiti in the background...

Any tips, guidance, whatever would be greatly appreciated.
