They were in my LCS last week and I flipped through them. The lettering doesn’t look quite right to me, but I’m so used to the Studio Proteus versions it could just be the change in font is jarring for me. They look gorgeous though. I might wait for the paperbacks just because I have GitS and GitS 2 at least once each already, but I never managed to get 1.5.
On the back cover thing, I think they’re the covers as they originally appeared in Japan. I’d need to dig out my copy of Intron Depot 1 to double-check, but the back of GitS looked like what I remember from it.
