As we were taking the above picture, we spotted a municipal clean-up-crew guy sweeping some more mini-posters off of the street and into a trash bin. So, we hope you enjoyed this advertising campaign, San Francisco, because you paid to clean it up.

UPDATE! This would be an excellent opportunity to direct your attention to Printable Cold Sores: do-it-yourself stickers that can be affixed to otherwise pristine lips on advertisements. Ads deface the neighborhoods; neighborhoods deface the ads.
