I know, AI is a controversial topic, and for many things, I'm really hesitant towards it as well. But when it comes to image restoration, it feels like it's a blessing. Will it bite me in the ass in the long run? Let's hope not!
With the help of AI, I was able to reconstruct the Last Crusade box background image (a blurry desert shot, for which I never found the original source) a lot faster and cleaner than before. Furthermore, I've utilized the original promo photo of Ford and Connery, extending it ever so slightly on the right side via AI (the original photo ends pretty much where it does on the original box). Of course, there's still a lot of manual clean-up, masking and color-correction involved, so thankfully this hobby is still giving me something to do.
Edit: I've included the sources I've used for the logo, a floppy scan from the LC Action Game (utilizing the same INDY logo as the Adventure Game), and the FM Towns version, for the full logo. Both found on Mobygames (scans by Servo and hoeksmas). The original box scan was provided by TomVDJ years back in this thread.
The next step will be adding the marbled paper frame and building several different versions of the poster.
Edit: What the hell, here goes.
With the tagline rebuilt from scratch (That's "Matrix II Bold" at 45% width, by the way):
