Not, erm... really mine per se. Maybe they found their way here via some big auction site via somehow or other, so, um, nope
I don't mind. I think that's grey enough. Just don't ever sell the images unless you buy the manual and scan your own images from it. I think the copyright on the original is long since expired. Technically I think the seller of the manual would have copyright over these particular images since they took them, but not over the manual itself. I'm just sharing them here because I love GRAFLEX-speak, and I hope to help further educate my fellow Star Wars geeks!
If you were to alter and cut and paste the relevant portions of the images out (and onto a new Star Warsy backdrop/border for instance), that would make those new images yours and you should be covered copyright-law-wise.
