Over at Ye Olde Message Boarde, a member snapped a photo of a local establishment's bathroom as the zenith of gross, and posted it to see if other users could identify it. We are blatantly stealing it and asking the same question. (Note: We have been in this bathroom, and while it looks almost cool and interesting in the photo because of the tagging and the mix of colors, rest assured, the texture of the wall and the smell both inhibit any pleasure you might experience at the sight of your fellow Philadelphians' creativity.)
Who knows where this photo was taken? Place your guesses in the comments, and we'll give credit to the actual poster of this photo when we get a right answer.
