Location is everything…
Unknown location* (and unknown original image source)—but I like it!
*Update: on 14 May 2010 I heard from Steven Hamilton, who writes: “I was browsing your blog and noticed a photo from my backyard! Just thought I’d let you know the photo of the face on the wall with the hanging ivy hair is in Columbus, OH, in Pearl Alley between Paterson and Oakland Ave., just North of Ohio State University… I pass it every day on my way to class.”
Thanks, Steven!
