All I can say is that the crumpling was almost certainly done to make the document appear more aged. Apart from that, it's hard to draw conclusions about when or why it was done. But it does seem that at one time CBS must have had more than one version of this document.
He also adds that the crumpled version has an address blacked out. Who did that, and when?
Again, I'm sure this is innocuous, but still . . .
