The attached photo post card was a souvnier from 1933 Chicago World's fair. I see how this trick was done - four mirrors and some strategically placed black curtains. My question is does anyone know if this was a live shot or done in some sort of an automated booth? Did it have a name and was it done in other places - fairs, carnivals etc? Or was this a one off set up just for the '33 World's Fair?
