Is there any in particular that you would recommend? I'll admit that I have a negative prior for AI upscaling, as I've seen a few cases in I think iPhone pictures where the AI added things that weren't there. Ideally I'd like to find the original pictures of the sets, as either they will be digital, or can be digitized without losing anything, but it looks like it would require a trip to the USA at the E. Young Research Library, and I'm not even sure I would be allowed to take copies.
