Retro porntech: Victorian-era nose-operated peepshow

"As the name suggests, this is a nose operated peep show. Originally made for an exhibition dedicated to embarrassment. When you look through the holes a rather boring picture of a Victorian naked lady is slowly revealed. What you do not realise is that the same time two 'decorative' cheek mirrors drop down unseen, two blusher pads come out and redden your face, thus guaranteeing embarrassment"
