5200 Battlezone Prototype Box

Although this box actually says Atari 2600, it is believed that this is the prototype artwork for the Atari 5200 version.  It was not uncomon for Atari to switch around artwork between systems for upcoming releases before settling on a particular piece.  Notice how the artwork shows the targeting sight of the tank which was not in the 2600 version.  On the right you can see a side view of the actual 5200 Battlezone box as seen in the movie Cloak & Dagger.
