Erstwhile comics artist Gray Morrow's cover for the Perry Rhodan book Fortress Atlantis (1974) reminded me of something else, and I finally realized it was the general layout of Robert Foster's cover for Davy (1964). A closer look shows that parts of it are actually swiped -- the torsos and legs of the figures are exactly the same on the two covers.
Nor a swipe, but possibly inspired by the same source I can't pin down, here is another Perry Rhodan that made me say, "Where have I seen that before?" The Wallace Wood page is from Dynamo #1 (Aug/66).
