Tomahawk was one of DC's many, many western characters who'd been around since the '50's, trotting along very nicely without anyone really noticing. Under the great Bob Brown, he got up to the usual Silver Age silliness everybody else did, such as fighting evil versions of himself:
Discovering dinosaurs frozen in ice:
Meeting The Frankenstein Monster:
And being threatned by a giant gorilla with a bow and arrow. Actually, that's a new one on me, that one.
Then, in the Bronze Age, he got a little bit of a makeover. Bob Kanigher came in, and remembered this was supposed to be a western strip, not Supes & Bats bouncing around in World's Finest, Neal Adams contributed some new counter-culture covers that looked like outtakes from Soldier Blue, and Frank Thorne did some of the best work of his life.
Ok, it's still DC pre-Jonah Hex, so no real surprises in the stories, but as Tomahawk protects the settlers of the Old West from constantly marauding Indians, alongside his Howling Commando's style buddies, one of whom seems to be an elf, it all feels properly authentic and right. And Neal & Frank are on fire.
