The Rawhide Kid #60

The Rawhide Kid charges headlong into danger on this October 1967 Marvel cover — penciled by Dick Ayers and inked by Herb Trimpe — as the Kid gallops full-tilt on horseback, pistol raised, with arrows flying all around him and mounted warriors pursuing through a cloud of dust. The cover promises "Massacre at Medicine Bend!" as part of what Marvel boldly bills as a six-gun saga thundering into a deadly Indian War. It's a visceral, kinetic snapshot of the Kid at his most hard-pressed, making this an easy pick for any fan of Marvel's Silver Age western adventures.
