The Whole Hole Trick by Karl Norman

A packet of eight cards is shown to have been mistakenly printed with "backs" on both sides ..... A big hole has been cut into the only red card; the rest are shown to be blue on both sides ... The cards are divided into two packets of four cards each .... and then the fun begins!

The red hole card changes packets back and forth ... the hole changes from a red card into a blue card (and back again) .... the red hole card impossibbly changes from hand to hand finally coming back to rest where it all starts ...
