The markings on the capsule are completely new and don't match up with any Star Wars written language, which is part of why this picture excites me so much; was this supposed to be the original Star Wars language, before Aurebesh?

Aurebesh's first appearance was ROTJ in 83, right? And even then, it's not really the same aurebesh as the more modern codification.

Anyway, keep in mind that the same film has English letters on screens, particularly the Tractor Beam controls.
