Leon,
I think your comparison is different.
To me, the comparison of the franked card would be more like if someone took the "Babe" from one sig and the "Ruth" from another and taped them together. If both are real, then I have no problem with someone deciding that's what they want for whatever their reason is.
You can see both parts of the franken card and the franken Ruth(my example), but you can't see the original ink of the underlying auto. How can anyone say it real?
Suppose someone could remove the ink. What if the original is fake as well?
How plausible is this scenario?
Suppose a father gets Ruth's auto on a ball. The pen is weak so he goes over with his pen at home. Later the kid enhances the auto because it's fading. Now we have a trace on trace.
