Page Publications' Modern Love Stories #49 reprints The High Life of Molly Brown, which originally appeared in Famepress' Juliette Picture Library #12:
Modern Love Stories #49 features a Keith Chatto cover. Based on previously established patterns I expect that there is an earlier edition of this story from Page Publications, and that Chatto would have been tasked with swiping the cover from the Famepress edition.
What really interests me at the moment is the high issue number of the Modern Love Stories #49 issue. The cover price $0.20, as per the only other issue in the series that I am aware of - Modern Love Stories #50:
Given the Famepress edition was published in 1966, and the Page Publications editions were published in the early 1970's, the basic math equation suggests The High Life of Molly Brown, and indeed a number of the issues in the Juliette Picture Library series, could have been published by Page Publicatons from say Modern Love Stories #1 onwards if they were loosely monthly issues as far back as 1966. But I don't know whether there was such an issue. I certainly haven't seen any in the relatively short time I've been following the Page Publications romance comics, and there are no such early issues listed on GCD or AusReprints - and James has been tracking these for much longer than I have. So I'm guessing that at some point, Modern Love Stories picked up its numbering from some previous Page Publications series.
Or maybe even from another publisher's series. This paradigm is evident in another high numbered Page Publications series, Love and Romance Library. According to AusReprints, this series began in 1951 as a Frew Publication and morphed into the Page Publications series c.1965 with the Candid Confessions cover title.
So, was there a Modern Love Stories #1 comic? And was it published by Page Publications?
