Show three poker size cards - two are blank on both sides, and one has the front of a lady on one side, and her back on the other side.
When you place one of the blank cards in front of the lady, she appears to stretch and get taller!
Then everything returns to normal size.
But the magic has just begun - a surprise awaits your audience! The lady card becomes a mini card and the lady on it is very small!
This trick is based on an original idea of Aldo Colombini.
