I have no clue who the artist is. Yes, it is VERY nice work! I love the little pumpkin icons for New Posts. And yes, I'll make sure to honk extra loud if they take more than one. 8) Lol nothing like scaring small children!
Personally, I am setting a bowl full of candy in front of my car. I will place a sign on it saying Take One. Then when a kid has their hand in it I will honk the horn of my car. Great Fun!
