Curious book, this one. Went by ,e in the day. Not the kind of book I would have looked twice at.
Joe Sinnott inked by Vince Coletta? This was 1963 and both were working for Marvel and inking Jack Kirby. Coletta was a reasonable choice on
Thor - he gave it a feel of its own. Joe became one of Jack's notable inkers but his style is vastly different from Coletta's. Here Coletta simply obliterates a great deal of Joe Sinnott's work - [Something he was often guilty of] you are only left with the layouts.
Interesting Idea for a romance book but a bit late in the day to start this kind of title.
