Looks vaguely familiar there. I wonder if there was any influence on the costume designer. Considering that the first one began in 78-79 the timing is feasible that the artist could have been influenced by the style. Then again, I guess the face isn’t so original that two people couldn’t have just come up with a narrow slit for an eye.
This issue of Perry Rhodan was released in 1970, and the illustrator was Gray Morrow, a prominent illustrator. The designer of the Cylon is Andrew Probert . Judging from this in depth breakdown of the design, I’d have to guess that it was a very vague influence if any. Most likely a coincidence.
