Quite a dog, that Tony. Continuing on from his successful work at Prize over the previous decade, Kirby did a lot of covers and stories for the Marvel romance books, including this early one inked by Vince Colletta.
This is also part of an informal set of artist themed Kirby romance covers, going back to Prize’s YOUNG ROMANCE #1 and Mainline’s IN LOVE #3. Any others?
[later edit, see this post at the S&K Blog for more on the artist/model theme]
