Lulu Marketplace

A spectator is invited on stage and asked to select a card, which is put in an envelope and pinned to a board. The performer brings out a page of adverts ripped out of a comic book or stag magazine. The spectator is asked to rip each advert off the page, to choose one and stick it to the board. Attention is then drawn to a sealed package that has been on display the whole time. To everyone's amazement - inside the package is a set of novelty x-ray specs - the product advertised in the selected advert! To test the effectiveness of the x-ray specs you put them on and see through the enveloped pinned to the board, reading the face of the card inside!
