License Plate Missing

So, a car has two license plates, but now I only have one of my favorite CUB 8 plates. I switched out the plates a couple months ago with generic ones. My goal was to get Dawson to sign one when he came to Peoria. As you can see from below, mission accomplished. But the other plate is no longer in my possession. What was I going to do with it, so I asked Dawson if he would like it. He looks at and says, "Illinois". My comment, "It's yours if you want it." He simply nods his head, says yes, and sets it down in front of himself.
