A lovely card stretching routine - very simple to do, because a little something does most of the work for you.
Have a card selected (totally free choice) and draw a happy stick figure on the back of the card. The spectator can even sign the back, too. Then you place the card back on the top of the back and add another card on top of it - the stretch box. You now stretch the card with the signature clearly showing. At the end, simply square up table the top card, the stretch box, and hand out the selected with the stick figure as a souvenir.
This is very simple, no difficult sleights, no difficult clean up. The trick is in a gimmick that works its magic automatically.
