This is a photo from 2006 of the sidewalk near the Gap at Powell & Market in San Francisco. I don't know who made the stencil (I also saw them a few other places).
This is currently among the top 50 best selling Moo holiday cards (scroll to bottom of the post & it later got an honorable mention and was part of their holiday card pack)
Make a MOO Greetings Card with this image and help raise money for Médecins Sans Frontières
You'll be taken straight to a page on MOO with my image selected, ready for you to customise and buy (doesn't work anymore)
