Two-fer Tuesdays: Mixed Messages Maybe?

A twice-monthly pairing of book covers that just seem to go together. Click on either of these images to open up an enlargement.



Never Love a Stranger, by Harold Robbins (Cardinal, 1964), the back cover of which can be found here; and Always Love a Stranger, by Roger Davis (Hillman, 1961), with the back cover posted here. Sadly, I don’t find credits for the cover illustrations on either of these novels. Can anyone identify their artists?
