As mentioned some time ago, colour register printing errors are relatively scarce as far as the K.G. Murray covers are concerned, especially compared to Newton Comics.
I’m fond of this Bumper Western Comic #1 cover. The blue faces and pink/green/yellow background virtually qualify the image as a candidate for the space western genre.
There’s a Leonard Cohen line that goes “There is a crack in everything/That’s how the light gets in.” Words to live by.
