I don't know if this has been mentioned, but a fax or photocier would drop out this information. The images are RGB mode, which isn'g surprising since they were scanned.
But the interesting question is when did the crumpling occur? It the original document was crumpled, a photocy would drop out all the grayscale information.
What this means is that the crumpled "original" was scanned by computer into RGB mode. Did CBS only get an electronic file? Or did CBS do the crumpling?
Intetesting isnt it, but a copier might not drop all of the information. Especially if the copier was set into a photo mode or was a non-digital copier.
