You know what's very odd about Mainline, kozmo?
The first issues of each title had VERY little Jack Kirby in them! This has ALWAYS struck me as extremely peculiar. Why on Earth, when launching their own line of comics, would they figuratively tie one arm behind their back? For example:
Bulls Eye #1 has a great Kirby cover, but the interiors are all John Prentice or Bob McCarty over, at best, Kirby rough layouts.
Likewise, Police Trap #1 has the prerequisite Kirby cover (or at least what looks like one at first glance - more Simon here, IMHO, than Kirby) but inside you find Meskin, Draut, Prentice, Bernard Baily(?!?) and Joe Albistur.
ALL of these artists are good, some even great, but NONE of them is Jack Kirby. So why wasn't he cranking out the pages to launch HIS company? I asked Jim Amash to ask Joe Simon that question when he did his recent interview with Joe, but Joe sidestepped answering it, not once but several times. Jim eventually realized that he wasn't going to get an answer, but the question still hangs in my mind.
