I currently have a lovely rendering of Abraham Lincoln on my back french door, and on the front window is a daubing of something that looks suspiciously like Lassie, though I'm not really sure. The more closely you look at the nose art, the more it changes.
And they keep adding to it all the time! Just when I was going to sell the Abraham Lincoln glass for (I'm sure) big bucks, Gunner went and added a tricorn to the top of his stovepipe hat. I mean, geez, I explained that it was the wrong history period, but he's such a tempermental artist that he doesn't care for opinions. I can't imagine what form Lassie will take during the course of the day.
Max doesn't actually *touch* glass with his nose, but much prefers to just blow all over and let the patterns of the landing nose droplets speak for his artistic ability. He's such a modernist. And the dashboard of the car? Totally disgusting (note: Max rests his head on the dashboard to make sure I'm driving okay, and don't bother flaming me for this as this has been HIS spot for 10 years and it ain't likely to change now)... dried white droplets on a black dashboard. Now, if there were anyone out there who could read these like tea leaves, we'd have a new niche in the dog world.
I *could* just erase the artwork by doing something called "cleaning", but they'll just start all over again, right?
