This Penthouse billboard, showing a photo of a woman's eye rotated to resemble … not a woman's eye, has been banned in Bulgaria due to its obviously problematic visual. Interestingly, Bulgarians really seem to weigh the pros and cons before complaining about an ad. Says one: "We understand that there is freedom of speech and freedom of expression, and that they have to be respected and upheld, but we cannot hide our contempt for the filth that is the Penthouse billboard."
