Flipbooks are fun, these flipbooks show a series of animation tests using the same running figure in different mediums. There are 8 variations of flipbooks, which one you've received is unknown until you open the five stick pack of gum-like packaging. Small and concise, these books are bound using eyelets designed for holsters/knife sheaths, because that's what worked best.
Each flipbook measures 1 1/8 in x 3 3/8 in x 3/8 in printed using a photo printer on cardstock
