There are a bunch of variations, but there are two that are most familiar. There would've been different types depending on the outlet... there was a very simple one with three glossy prints that was distributed most widely to things like college newspapers. A fancier version with five (or seven?) glossy prints went to larger newspapers. But there would've been a variety of specialied ones that included slides (for magazines or papers printnig in color) and then versions with the EPK for TV stations and linear productions. The slides are difficult to track because it was the practice of most papers to archive them separately... so that sheet of them was usually divided up and filed away for reference (which is why the same pictures now show up in stock footage collections, they're the result of papers ditching their old slide archives).
