As Rob A. pointed out.......the red backgrounds of Cobb (red portrait) and Boss Schmidt (portrait) are not uniformly discolored.
Yet, cards below & above them, and cards to the left & right of them are discolored.
I suspect that the discoloration on some of these cards is due to the long-term affects of GLUE seeping thru into the fronts of
the cards and chemically altering their colors. Especially, the Cobb and the Boss Schmidt cards......as, the pattern of their RED
discoloration is indicative of this effect. If you recall, we have previously discussed this "glue effect" on Net54 in prior threads.

I'm not referring to the kind of posters you displayed....I dig the fading of those type of things.
My contention is.....that Rob A. first made the point of the red Cobb and the Boss Schmidt cards having non-uniform discoloration. I observed this also; and,
added that fading due to "sun exposure" does not result in this kind of effect. We attributed this type of discoloration in these two T206's as possibly having
been caused by the chemical reaction of the glue used to mount these cards on that poster.
So, I am not sure of what your point is ?
Anyhow, since no one here has yet to address the Cobb and Schmidt cards' discoloration, perhaps we can get your take on these two cards on that poster
exhibiting a different effect than the others ?
