Steve---on the Campos, I have a black star and one of the missing front top left border versions. But I also have a partial black star, or at least one where there is only a small amount of black on the star. Not sure what that means.
Point being only that determining if a defect was intentionally corrected or just transitory is not always determinable.
I have never thought the King was intentional. Bob put it in the catalog at time before the internet and ebay demonstrated that there are thousands of print flaws like the Herrer and Bakep out there and that the definition of a variation needed to be narrowed for listing purposes.
PSA did not help the narrowing process when they recognized the 61 Fairly green smudge in the baseball on the back
If they are recurring I try to collect them whatever anyone else may call them
. Always enjoy discussions like this
