Improvements in the devices for obtaining changing or animated images of apparent movement, consisting essentially of printing the graphics based on lines, on transparent sheets of suitable material, provided with references to means that facilitate their correct position by superimposing them , making said impression in such a way that the lines of one sheet are out of phase with respect to those of the other or others, so that, once superimposed, lines are interspersed with each other, thus determining a composite graphic, visible by transparency to through the corresponding sheets, on which the fluted plate or observation grid is superimposed.
