If you like collecting animation storyboards from Flintstones, Simpsons, Disney plus others they you are probably an animation art collector. But you did not need me to tell you that. The collection of animation art goes beyond storyboards. If you are just starting out check out this site for definitions of animation art that will help you in your exploration of this field of collecting.
Here is a really nice gallery of animation art by an avid collector. I found it to be comprehensive and educational. I also found an animation art marketplace. Here you can buy and sell your pieces. Of course you also have good old Amazon, Etsy and Ebay. If you are thinking about it and want to read more on this area of collecting consider checking out a few of the books listed below.
