Yep San Diego. Here's a link to the poster: [link]
The company who printed them, Iconoclast Editions, does 1 cent posters periodically (plus $8 shipping & handling of course) to hype up big openings. They are usually printed on lesser quality paper, but for the price it is hard to lose. They also did one for the Supply & Demand show that Shepard Fairey put on & the Ed Templeton photography opening.
BTW, I like your shot better. The slightly off-kilter angle & the handicap spots add to the image.
I took a picture of each individual at an angle from the staircase to the right, which turned out pretty good. I'm planning on uploading them sometime soon. The patterns and details in each person and their clothing is amazing and you can really appreciate it in the closer shots I took.
