While communicating with Mr. Blue on his laptop, Bruce Banner (Edward Norton) would often look at this printed picture of Betty Ross (Liv Tyler) he printed off of the Internet. Production noted this as being screen used by actor Edward Norton.
It's actually a printed page featuring some text and a photo of Liv Tyler as Prof. Elisabeth Ross while attending his class.
There's some sort of advertisement on the back. We can actually see both sides on Banner's desk (staring often at it) and when Emil Blonsky (Tim Roth) hands it to General Ross (William Hurt) and he folds it...
Item can be screen matched thanks to the bends and scuffs on certain parts of it.
