Al Williamson's Savage World

Savage World is an interesting one. At first, it seems to be 'just' another wonderful Al Williamson piece, with the added attraction that it stars Larry 'Buster' Crabbe. But there's a lot more to it than that, including the fact that it covers nearly the whole of comic history, having first appeared in the '50's, then being seemingly endlessly reprinted in the '60's, '70's, '80's AND '90's. Not bad going for a simple 8 pager. Plus, this actually isn't Williamson flying solo.
Here, from Kitchen Sink's Death Rattle, is Al in conversation with Dave Schreiner, to tell the whole story:

 And here's the strip:

And, as we're all completists here, how about a gander at the aforementioned rewrite by Bruce Jones, from Alien Worlds. You got yerself some brass ones, don't'cha Bruce, rewriting Wally Wood & Al Williamson?

Behold The Man

Here, with suitably controversial cover, is Roy Thomas and Alex Nino's fantastic adaptation of Michael Moorcock's Behold The Man. I can't really add anything to Rascally's introduction here, as he says it all.
Like everybody else, I throw the words 'classic' and 'masterpiece' around a lot on this here blog, but honestly, Behold The Man is both of those things and more.
And, on a lighter note, it's obvious that Nino had no idea what a Teddy Boy was when he did this piece.

Repent Harlequin! Said The Ticktockman

And from Unknown Worlds Of Science Fiction, here's Roy Thomas & Alex Nino's adaptation of Harlan Ellison's double award winning classic "Repent Harlequin!" Said The Ticktockman. At the time, Ellison himself, though a huge fan of Nino, went on record as saying he didn't like this version of his story much. The lead character Everett C. Marm aka. The Harlequin is, as you'll see, the living embodiment of chaos in a perfectly ordered future world. Ellison's complaint was that the entire strip was insanely chaotic, thereby diluting the repressive, drone-like order of the setting, and the story's message. And you can completely see his point. BUT. It's Alex Nino, Harlan!

Alex Nino was born to draw bizarre science-fiction, him being from another dimension and all.
He's one of those artists whose work is so personal, so unique to them, that you genuinely can't see how he does it. Think about it, Kirby has hundreds of imitators, as does Kane, or Perez, or Buscema. Nobody tries to draw like Nino, because it's impossible. To do what he does, you'd have to actually be him.

Like Master Of Kung Fu, most of the material from UWOSF will probably never see print again, tied up as these adaptations are in copyright wrangling. So don't hold your breath waiting for an Essential Marvel Sci-Fi, and enjoy this stuff where you can.
