Hedgehog in the Cage
by Clarence A. Worrall (?)
Though the puzzle is strongly associated with Czech Republic (in Czech: Ježek v kleci), it has its origins in the USA. The first known patent to its model was obtained by American inventor Clarence A. Worrall in Philadelphia, PA, in 1896. The puzzle arrived in Czechoslovakia around 1935 and entertained huge popularity in the country as an organic part of one of the most successful Czech comics - Rychlé šípy (Rapid Arrows). Can be in plastic, metal or wood versions; and the object is "simple" - take the "hedgehog" out of the "cage".
