IMHO opening two crowdfunding campaigns for "Fistful of dollars" and "Duck, you sucker!" will successfully raise money in a week or two... if there is some interest in preserving those prints, of course...
About GBU: if needed, I could try to restore the scanned print to a good shape; don't know if I will be able to reach Mondo or MGM 4K quality, but hey, we are all fan restoration hobbysts here, aren't we?
