There is another picture of Little Eva with a column, so I don't think that the column itself is as important as Little Eva is:
Maybe it is a field element, but I don't want to speculate on that right now >.>
The image being flipped probably does have something to do with the game, though I don't know what. Maybe the two sides of the field are flipped versions of each other? I'm just saying this because they DID give us a pretty-much-straight-off-of-Google picture of the Opah two years ago, and they would be kind of ignorant to not expect us to figure out any picture (that wasn't generated by them) hint really quickly, no matter what state it's in.
What I find kind of interesting is that the picture covers a longer area than the one that is on the record cover
. Look - in the image provided by FIRST, you can see from her right elbow down. I wonder where they got this picture from? I doubt it's important, but now I'm rather curious.
