Pocket Kinetoscope 'Series C' Flip Book, by American Jubilee Company, London, End 19th Century

This Flip Book is made by 81 little photographic sheets, on which are shown two prize-fighters on the ring with the referee.

Flip book is usually a little book with a series of drawing or photos that change gradually from one page to the next. Holding the book with one hand and flipping its pages with the thumb of the other hand, the pages are turned rapidly, and the pictures seem to animate, simulating motion or other thing, like facial expressions or changing colors. This is made possible by the persistence of vision.
