I’m amazed they got away with putting “Star Wars” on the cover, tbh.
And it’s a discredited genre now, but in the 70s the line between porn parody SF and actual SF was very thin indeed. There’s a reason several future Star Trek VFX artists worked on the 1974 Flesh Gordon.
I thought it was because they needed the work pretty badly, as there weren’t a whole lot of FX laden pictures being made before Star Wars? Aliases were used in any case.
