Those are indeed better than the ones I found if only because of the logos but I really prefer how the text doesn't get in the way of the faces on doublex's. If I had the talent I'd take a crack at making a copy myself. I've always really liked these covers for some reason. Very elegant and restrained, even though they're much like the photoshop jobs people despise so much today.

edit- does anyone have those stylized THX/Lucasfilm logos in high res? I've made my own custom versions of this set but the spine looks a little empty without them. I'd of course be happy to share if anyone's interested with the finished project, but it's a pretty quick fix. I just upped the contrast so the black levels were consistent and took the fronts from Mackey's folder & the backs from the set I had.
