The signboard can be seen behind the frosted glass. A little above the center of the sign, in somewhat large red letters, it says, "This image should not be viewed by anyone under 17!".
Below that, in black letters, it says, "Mosaicing without clear standards is an infringement of freedom of expression!!"
Below that, in even more red letters, it says, "Are robot figures more dangerous than bold skin exposure or underwear?" The sign is blurred through the frosted glass.
