Back on ye olde Genesis, the game Columns 3 has a peculiar image on the backside of its box:
This screenshot (located on the top right of the box) depicts both players having pieces that have extra halves on the top and bottom.
Normally I would dismiss this as just a bizarre probably-capture-artifacting thing, but my memory assures me that it absolutely is possible and has occurred once before, and none of the other images on the box have any image quality issues.
So... I'm asking if anybody has any definitive proof either way. The image below is pretty low-resolution, but I don't think I have my box around to scan any more.
