You're looking at the cover of the National Geographic magazine from March 1984. It contained a hologram of the American Eagle on its cover, produced by American Bank Note Company (holographic division). Eleven million of them were sent out to recipients around the world.
Have you perhaps found a National Geographic hologram issue? Are you curious as to its value? I would have to say that, updated in September of 2011, expect to pay about $8 to $15 for a clean issue in the USA. This would be a retail price. Therefore, if you need to purchase one in order to sell one, you're going to have to find one that's going for $4 to $8 to turn a profit.
This type of hologram is called an "embossed" hologram. They are massed produced on a very thin, mirror-backed mylar. As you move the hologram (or the item that the hologram is affixed onto), it changes colors through the rainbow. It is basically the same type of hologram that is found on credit cards . . . only larger. They are still used in packaging, and are even more abundant for security (product authentication).
The March 1984 issue of National Geographic was considered, by many, to be the pivotal one that opened the door to further holograms on the covers of print publications. It is debated whether it was the very first, since an amateur photography publication in England placed a hologram on their cover sometime before Nat Geo. However, it can be agreed upon that the National Geographic cover was the largest production run of a holographic cover in the world at the time (at 11 million units). It was so popular with its readership, that they ran two more issues over the years with holographic covers. All are highly collectible.
