A few years ago, I spotted AW member J. M. McDermott's book Last Dragon at the UCLA Books store.
I took a picture, and posted it (I note that in the picture, I am holding the book upside down; this typical for me).
A few weeks ago, I was on Twitter with another AW author, and tweeting about my desire to go to Barnes and Noble, and look for her book in the wild; she encouraged me to post pictures—and thus, this thread was born.
These are pictures I've taken of AW author's books spotted "in the wild."
I encourage you to post similar pictures. I'd particularly encourage folk to post pictures from indie bookstores.
Post the actual image up at Photobucket or Flickr, or your own site, and then just link to the image here.
Note the book, the author, and if you're comfortable with it, the name of the bookstore, or if it's an indie rather than a chain.
