This one, I remember from my childhood years. Marvel was jumping onto the Godzilla bandwagon and had their own version of the character in a comicbook for about two years. The title was drawn by Herb Trimpe following his classic run with the Hulk, before he went through a few other projects before doing the GI Joe series with Larry Hama.
If there was one thing that Marvel should've gotten around to doing, they should've had the Big G go up against the Hulk. I wonder if the Hulk would've gotten smashed? Probably not!
I remember that, i also remember somebody at Marvel did a funny illo of The Hulk vs. Godzilla, Showed the Hulk imbeded in the ground in big G's footprint! while Godzs is walking away, Hulkies screeming as soon as he pulls himself out of the ground, Hulk will smash or something like that, So long ago and it was geniuenly funny!
I could vaguely recall seeing some art to that effect. I'm not sure if it were in one of the fanzines, or if it was a Marvel pinup of that era. The Godzilla comic lasted only two years during the late 1970s, but it was wrapped up properly. (The superheroes won the battle, yet Godzilla swims away relatively unscathed.)
