There is an interesting proof sheet on Ebay with a rare proof that is not even mentioned in the listing.

The has been higher, but the price is reduced to $500 now. Collectors from that set are familiar with the Darrell Jackson Black Hat/Red Hat(multiple) variations. Darrell Jackson card on this sheet pictures a white player. That photo was corrected before release.
I would guess that they switched the photo and realized the real Jackson's cap didn't match the other Twins?
The Willie Wilson card may be different as well but I would have to confirm that.
