I found it very interesting that all of these covers present the female figure at the same angle; two are posed virtually the same. All of them show women in some sort of jeopardy at the hands of a man, physical in two cases, almost physical in a third (she’s being menaced by his shadow as he approaches). One appears to be emotional jeopardy, instead (the man’s back is turned; she’s been rejected).
