Quick Update: Thanks to some very experienced and helpful folks, I have actually been able to determine I own three out of SIX Last Unicorn reels rather than the three out of TWELVE I thought I had (due to labels on the reels themselves).
This means I am looking for print 517, reels 1/2/3 to complete the half print I have. But again, I will take trailers, odd reels, partial prints, full prints, or anything else TLU related anyone might be looking to rehome, pending discussions on prices! 😃
