DIA70xL160mm, China
This is a Chinese version of the thaumatrope; by pulling the string that is attached to the axial of the circular frame, the image inside the frame will turn over and over again. The 2 images from both side of the frame will appear as 1 due to the persistence of vision. The momentum of the spin will cause the axial to spin at the reverse direction result in a prolong animation.
