1958 Topps Hank Aaron - BLUE background??

[scooter729]

Hi guys, posting this one on behalf of a friend who's not a member....

He recently picked up the pictured 1958 Topps Hank Aaron card. Typically the card has two variations - white letters or yellow letters for his name. However, in both cases, the card's background is GREEN.

In my friend's variation, the name is white, but the entire background is BLUE! I have never seen a version like this.

Has anyone ever seen anything similar on a '58 card, Aaron or otherwise? The card definitely seems legit, so maybe there is a version where along with the yellow missing from the name, it's missing from the run to make the green color (since yellow + blue = green, so no yellow would just be a blue background).

Would love to hear some thoughts on this one. Pictured is the standard card along with the blue background variation. This isn't just a scanner issue or something - this is really how the blue background card appears....
