Heritage Auctions invites you to own a literal piece of Transformers history with several auction lots. These are auctions for production cels that were used when making the G1 Transformers cartoon from Sunbow/Marvel. These are all from the episode "A Prime Problem" and most include the master background, which makes them even more pricey. That's because while there were about 25 painted cels per second of an episode, only 1 painted background was used per scene/shot.
The prices are already in the hundreds but if you want to bid on them, or just check them out, here is the link:
