That’s my Pop – Arty Severtsen

A charming close up effect.
Two miniature playing cards are shown to be taped together face to face forming a channel thru which a third card is pushed. A pop-rivet (which looks like a miniature sword) is then pushed through all three cards which have a hole in the center for that purpose. The performers frees the middle card without removing the rivet. Everything is then handed out for inspections of needed.
A clever idea by Arty Severtsen. It would be easy to make up your own set using regular sized cards once you see the method.
