Battle Beyond The Stars (including one foreign sheet - German? - that shows the title as Sador - the name of John Saxon's villain!)
I really love the painted U.S. one-sheet. Seriously, weren't movie posters so much cooler before Photoshop? (Anyone know the name of the artist?) Enjoy!
(I just noticed that unlike the U.S. poster, the International art doesn't feature Nell, cinema's only spaceship with breasts. Hmmmm....)
