(Cambridge, MA., September 2010)
Signs and sign posts are a good vehicle for unapproved art. This was taken September 11, 2010, and still exists in good shape.
Graffiti in Cambridge, mostly. There's a lot to see when you take the time to look.
Note that this blog is under construction, and I'm in the process of adding photos as I took them, starting in 2011. It's going slowly! I've switched formats over the years, so please bear with the inconsistencies.
