@sayomgwtf I lived in Studio City as a teen, not too far from the Hanna-Barbera studios. Once I stopped by there and went dumpster diving (it was unlocked, totally open to the elements), and came back with a large box filled of discarded Flintstone cels, most of them in sequence. Also a couple of indoor water color backgrounds. I set up my Super-8 camera and reanimated several of the sequences for fun.
Unfortunately, a few years later my mother did a Spring cleaning and tossed the entire box!
