Well, more like lollipop red, but still pretty cool. Done last week to promote the fourth season of a show I've never watched. I don't know the city, most probably Bucharest. Certainly better than this confusing True Blood vampire umbrellas stunt staged last year in New Zealand. Ad agency: Unknown.
Update: Done! For Dexter three years ago.
Update: Also Done in Bucharest last year (same fountain?) to promote Hemophilia awareness. Probably where they got the idea from.
