First of all, huge, honking credit to u/MadDroog, who I believe took these shots using books from his personal collection. The main point is to show the original American editions and then how they looked in the French magazine.
And yes, that's certainly Robert Crumb's notorious Fritz the Cat on issue 15's cover, but you can indeed catch a glimpse of Corben's story in the lower right teaser.
Evidently to cut down on costs, the magazine used a simple color scheme throughout, and in Corben's case, colored his B&W art themselves with, let's say it-- less than ideal results. :P
So we have both Crumb and Corben seemingly popular in France by at least the early 1970's. I'll see if I can find some issues to see who else might have been included from 'non-BD' countries.
In terms of Corben's work, I find it just amazing. It's full of life, and drawn with a loving tenderness you rarely see in comics. The art was usually absurdly intricate, but even when slightly-rushed, Corben saw -forms- in a way that few other comics artists did. Probably not surprising really, as he had a degree in fine arts and first started working as an animator. I'm also sad to say that he passed away recently at 80yo due to heart surgery. RIP to an utterly unique legend.
As an upcoming treat, I think in a day or two I'm going to post a 13-page chapter from his Denz saga, even though it's American-produced. The art is ridiculously, utterly unique, and here's a sample page:
That means a lot to me, thank you!
