CAPTAIN AMERICA#68 continued the new team of Captain America and Golden Girl. The story was a little weird. Weird stuff and horror comics were supposed to be selling at the time. The last issue of the original run of CAPTAIN AMERICA would become CAPTAIN AMERICA'S WEIRD TALES, only Captain America wouldn't be in it any more, just the weird stuff.
The cover doesn't have much to do with the story inside. That happened a lot in the old comics.
In the third panel, Captain America is shown holding onto the edges of the shield as if there wasn't any sort of handle on the back. But on the rest of the page he's gripping the grip on the back of the shield, which is what he's supposed to do.
