"Circus" is a book-game for children based on poem with the same tittle. The author of the text is Michał Byliniak. On every piece of cardboard you can find a part of the text and a pop-up illustration. Children can link parts, and try to geuess or remember the poem. I have put the hidden numbers on illustration to help children in the game. In the box you can find the instruction and the poem in one piece.
