Before The X-Files, there was...Quatermass!

I've wondered where some of The X-Files' wilder concepts really came from.
Chris Carter has acknowledged a variety of influences including The Twilight Zone and Kolchak: the Night Stalker. Curiously, while there's a lot of mood and atmosphere directly attributable to those sources, there's very little of the actual concepts or plots from them in The X-Files.

This is not the case with another sci-fi series...
The 11th Hour Web Magazine did a story about similarities between key plot points of The X-Files (both the series and first feature film) and a group of four tv mini-series from England (all of which were also made into feature films) about Bernard Quatermass, a scientist fighting both aliens from beyond and his own disbelieving government superiors! (sound familiar?)

Whether or not the copying was deliberate, it's there! (IOHO, I agree it's more than coincidental!)
Thus, we consider Nigel Kneale's Quatermass series to be the direct ancestor to Chris Carter's X-Files both in concept and content.
In that spirit, we at Atomic Kommie Comics™ present a group of the posters of the predecessor series to The X-Files including...
The Creeping Unknown (Quatermass Xperiment), Enemy From Space (Quatermass 2), and Five Million Years to Earth (Quatermass and the Pit) on a variety of kool kollectibles!
We've been unable to find a poster for the final movie, simply titled Quatermass, which had a brief run in the US. It was an edited version of the final miniseries entitled Quatermass Conclusion, which ran in England, and is not a remake as the other films were!
