So I found this while cleaning up today. It's a box that was used by Konami to ship NES cartridges to distributors.
As everyone likely knows Nintendo limited the number of games a publisher could release each year, so Konami set up a shell company to increase the number of games they could release. Ultra was therefore the "company" that published Metal Gear.
This particular box once carried 24 cartridges of Cyber Stadium Series - Base Wars, which means this box is from 1991, a mere 24 years ago.
I have the game in the collection, and it's not objectionable.
