The Play Ball metal lunchbox was also a game, in that the back of the box (not shown here) showed a graphic of a baseball diamond, with a scoreboard along the top right and the rules at the bottom left. It also came with a spinner and four game pieces (shown). There were a few different lunchbox-games produced during this period (see also Campus Queen).
Note: The Play Ball lunchbox was nearly identical to the Official MLB kit, but without the new title in place of the MLB logo.
The artist on this lunchbox was Nick LoBianco.
