Inspired by Cram's "Nobody's Looking" poster, this is designed to be printed and cut in half for double the gasm per page. Stick it up anywhere there are security cameras. Add whatever stamps/calls to action/marginalia you like, and I will take requests for variations on this theme (more background, less background, alternate fonts, etc.). As always, pdfs are a little nicer on your printer and have been checked for proper embedding.
