Star Wars Vintage Darth Vader 12-Back Sample
"This Darth Vader action figure with the marking “Kader, PP, 11/28” is the production pilot reference sample from Kader. It is essentially the only remaining sample from the production pilot, making it a one-of-a-kind final evaluation sample. This also means that it is the very first 1977 vintage Kenner Darth Vader production unit in existence.
Woah. That's the kind of piece dreams are made of. edit - malware link removed
