Sam Lloyd Puzzles ... (1)

This book - The Geatest Puzzles of all Time - which I bought many years back has had been gathering cob webs on my book shelf until yesterday evening. Truly, I am still fascinated, especially with Sam Lloyd's creations.

The "Get off the Earth" puzzle (above) is one of his most popular creation. The original was made of cardboard, with a rotating disk in the middle. The Chinese warriors are partly inside, partly outside the disk. If you turn the disk, one of the thirteen warriors mysteriously disappears! Where did he go?
