Wait a minute, did that say PHOTOGRAPHIC, as in from a photo of the Great Old One? Well bust my britches and buy me a new white jacket with extra long sleeves, but this here site claims to have made posters from photographs.
I think there may be a certain Inspector LaGrasse that might want to look into that one. Either that's false advertising or something else sinister. I hesitate to say more sinister, because what could be worse than expecting true revelation from one of the elder gods and finding that it's a hoax perpetrated by just one of Cthulhu's many followers, bent and twisted as they are? Huh, I ask you.
BTW, I don't know why I switched into a kind of affected country accent just then.
