Do you think the glue is positive, or printed in? I'm not sure because of the little white fringes, that suggests it could be inverted. But then the actual cement residue would have a slight blue color, which doesn't really make sense. The stuff starts out clear, and I've read stories of old cement turning yellow or brown in the bottle, so I'd assume that like many adhesive compounds, it would likely yellow as it dries?

Good question, I have no idea. And you're right about the glue turning yellow or brown with age so it wasn't as visible at one point. That coupled with the low quality of the 35mm bootleg could be a reason for not seeing them but I don't think so in this case as the bright edges would probably be visible at some points despite its quality.

Please re-check the ISR SWE, specifically the shot of Luke turning the lightsaber back on after putting on the helmet. Russ' capture of the '91 UK LBX VHS seems to lack them, but it's also dark, fuzzy, and compressed, so I can't tell whether the splotches are truly not there, or if it's just too obscure, like with the glue marks we thought weren't there but actually were.

Not able to post any screenshots at the moment but I skimmed through it again and yes, the splotches are definitely there. It does however contain some frames missing in the JSC. So the ISR SWE is something that can be used to patch missing frames. More glue frames. Yay! ;)

I'm also not sure which pressing it is, if I recall correctly there are three of them - Pioneer USA & Japan and Mitsubishi.
