The film Star Wars wasn’t marketed as “Episode IV: A New Hope” until around the time the prequels were released. So they definitely would not be OOT.
The last OOT VHS release was probably the Faces set.
The Faces tapes say A New Hope on them, but the Laserdiscs don’t for some reason.
…*checking for verification.
Okay, on the spine yes. But only on the spine. And the 1997 Special Edition VHS sets did not say “A New Hope” on them at all.
The whole trilogy lacked the episode numbers until LFL started marketing Episode I.
