The members of this LiveJournal blog community specialize in finding and posting genuine advertisements and posters from old newspapers, magazines, and what have you. Not only do they prefer the older the better, they especially love the stupider ads! Blatant sexual innuendo, misogyny, racism, political incorrectness, scams and rip-offs, propaganda, and scare tactics will make these guys howl with laughter and beg for more. A bulldada treasure trove!
