Here you will find my collection of Cels!  I've set this up by series, for ease of navigation.
If you see anything here you'd like, I'm open to offers of trade and sale, HOWEVER some of these have sentimental value and I won't be able to part with them. ^_^  Thanks or curses to David, who really got me into collecting these money sucking pieces of plastic. 

You may ask, what the heck is a "Cel"? 
Cels (or celluloid) are painting on transparent plastic sheet used to create an animation. Each cel is one "frame". They are filmed and then put behind one another to give the illusion of a continuous motion..
