I have swung both ways on this. I have one but have come to believe most are faded. There are color gradations of the blue, but that could still be consistent with fading. If it was a sheet error there ought to be more of the same defect showing up on a lot of cards. I know there have been some.
And the number of Aaron's showing up leads me to believe some may be intentional creations.
I hope you are right Leon but I would bet money, based on the info in this thread, that most of these Aaron's are faded and that telling a legit production color defect from a faded card would be virtually impossible
But I still plan to hold onto my Aaron and Mays because I like mysteries and oddities
