Baseball was released in two different box styles: The older (original) box was significantly larger than the second (smaller) version, and had a large flap that folded out from the left side of the box. The large version had the game packed in styrofoam blocks, where the smaller version had the game packed in a plastic bubble-wrap bag. (Several of Mattel's earlier handhelds went through this change.)
