20th Century Panties
The magician shows two red silk handkerchiefs, knots them at the corners and asks a spectator to take them and tuck the knotted part into her dress, being careful not to let it fall off.
Then he shows a third, different colored silk scarf and makes it disappear completely, with the hint that it will reappear knotted among the other silk scarfs.
But when the magician steps behind the spectator, grasps the hanging ends of the silk scarves and pulls them out, a pair of underpants tied between them appears!
A big surprise and lots of laughs are guaranteed!
Very nice execution. Comes complete with two prepared and two regular silk handkerchiefs. German instructions.
