Collecting Prototypes: Tips and Legitimacy?
 

Hi everyone, I've been looking into collecting prototype figures and was wondering if anyone has any experience or good resources. Looking for stuff like Marvel, Star Wars, TMNT, DC, but anything cool really. I see plenty of listings on eBay for tons of early unpainted prototypes from China, are these real? Or just newly molded or paint-stripped figures?

Also feel free to share some photos if you've got any.
