I never cared all that much for either the Jung or Hildebrandt posters, though I
do have the '82 re-release poster, which re-uses the Jung artwork. I got the poster mainly because that's the year I first saw the film, and it has a nice silvery-blue metallic background.

I still love the White/Struzan '78 "circus" poster best. It's a masterpiece, imo.
