T206 upside down backs "should they be on the back run?"

[Blitzu]

Mrvster,

I can see your point and to a degree understand that maybe a non issued list vs a issued list could be contrived. Although, my qualifications for the current list were never solely about being factory issued or not. The basis for the list was being substantially unique to all the rest (even color variations, purposeful or not). That brings me back to my point that the upside down backs or upside down fronts are not unique in any other way from any current card already on the list. That's why they don't belong and this is why the browns, cobbs and blanks are currently on that list. They are all unique from any other known back.

Also, I'll say it one more time, who's to say the fronts weren't printed upside down on those?
