Juliette Picture Library #4 was published by Famepress with a cover date of February 1966.
Page Publications published the story The Heart Decides under a new Keith Chatto cover in Romance & Love Library #2:
Page Publications republished this story a short time later under another Chatto cover in Marvellous Love Stories #1:
It's not too hard to guess which of these three scenes accurately reflects the detail in the story. And probably not too hard to guess which I prefer. So let me just say I look forward to discovering that Chatto had occasion to swipe the image on Juliette Picture Library #4 for an earlier edition of this story, and that he also had occasion to provide a cover for a $0.40 Page Publications edition.
