I purchased a Super Metroid cart off of ebay about a month ago and I noticed that it has a misprint on the label that I've never seen (or even heard of) before: on the 'E' in 'super', there's a small yellow 'o' shaped misprint on the bottom part of the letter, just above and between the 'R' and 'O' in 'metroid'.
Picture here
Here's one that's slightly closer
Before now, I wasn't even aware that any Super Metroid carts like this were around, or that there were any known misprints on Super Metroid labels. It's my impression that Nintendo is usually pretty good about catching this sort of thing. I just thought that this was interesting and figured that I would share.
Does anyone else happen to have one? Has anyone heard of this misprint before?
