UPDATE 6/3/09: I ran across an article on the same thing today:Decades of beefcake, bodices, and Harlequin romances which mentions that the majority of the artists creating these covers were male.
I just found this on CNN, and thought those of you who write romances might be interested in this video on a Harlequin books cover art exhibition:
And here is a slideshow with a selection of covers from Mills and Boon’s 100 years in publishing. You have to scroll down the page to the sidebar on the right to find it. Some of the titles are side-splittingly funny (“Grace Before Meat”??? I ask you…)
We now return you to your regularly scheduled programming.
