Re: 1/2 - why would they scan that instead of something internally at Lucasfilm? Is it possible it’s a print from one of the ILM people?
I would presume that #2 would be in the archives of Lucasfilm, along with the IB Tech print. IIRC, it’s that fabled IB Tech print that is the source for the '77 scroll in the GOUT and OOT footage for Empire of Dreams.
