Since I've started working with Dick on his collection, some of my favorite pieces to study and work with have been Praxinoscope strips. As you can see in this animated set, the images are impressively rendered, and the actions are both charming and convincing in their motion. These strips were produced by artists who had none of the technological conveniences of a modern animator such as myself. I am constantly amazed by the refined technique that can be found in these works of art that predate the likes of Winsor McCay and Walt Disney by several decades.
You can find these praxinoscopes and many others on the collection website.
