CONQUEST OF THE EARTH (1981) Theatrical Posters

I'm kind of amazed that I never stumbled onto this before, but here are a couple of posters (British quad at top) for the feature film compiled from the premiere episodes of Galactica 1980.

I wrote about the Battlestar Galactica "movies" a while back, and I've seen the poster for Mission Galactica: The Cylon Attack many times, but this is the first I've heard of or seen any promo art for Conquest Of The Earth.
