I think the shredding stopped half way through - probably a dead battery.
My first thought was "well is the sale still valid?".
So why does the shredded portion look a different colour from the unshredded part? To me it looks like there's 2 paintings, one shredded and one normal? So they may be able to do this trick repeatedly?
