I was looking for swindles in old magazines and found this ad in a 1942 Sphinx:
Magician explains that modern methods used by radio programs in offering premiums to increase the sale of soap is really an old story.
He now proceeds to demonstrate a "Soap Sale" as conducted by "Soapy Sam" confidence man.
He requests the loan of a bill of any denomination and has it marked. Six bars of soap are introduced.
The outer and inner wrapper of one is removed and the borrowed bill is openly placed on the soap, around this is placed the inner wrapper, and finally around this is placed the outer wrapper. Its appearance again is identical to the other bars.
The bar containing- the money is mixed in with the other bars and both hands are shown to be perfectly empty.
Performer explains as the "main" prize has been "donated" by a member of the audience, he will give the second prize . . .
introducing a sealed package of Ivory Flakes, which is handed to someone in the audience.
The audience is now requested to select the bar of soap containing- the money. All are finally chosen and upon unwrapping them, it is discovered that none contain the borrowed bill.
The person holding the Ivory Flake box is requested to cut it open, and upon spilling out the contents the borrowed marked bill is found therein . . . spectator removes it himself.
No fake bars of soap . . . no switching of bars at any time. . . no switching of bill . . . no assistant required. , .
Has anyone ever seen or done this? Just curious about Berland's method.
