I've never seen a photo of Montana wearing the modern red jersey with white and black trim, and from what I understand, the Niners updated their jerseys to include black trim AFTER he left the team. Yet there are Montana gu cards out there that have black and white sleeve printing on the jersey swatch.

I don't think they're bogus because I've seen them offered by different sellers and this jersey version is used in different sets I've seen.

Any ideas?
