Quoted from Cybergoonie:There's a sign that strictly states not to deface the pins.....so there goes that theory.
As someone that has worked with FECs, trust me, the running joke was guests don't read signs! Everything else has graffitti on it...operator had to have known his pin was going to get it too. Hopefully when he goes to sell it he will make some mention of "slight issues with cabinet art...easily repairable and $100 discount is taking that into account...mint otherwise!"
