He took a picture of each statue with his iPhone.
He printed a copy of the picture with his portable Photo Cube™.
He framed the picture and added the inscription: "This is a statue. It exists in your woods. It is also a tree. Chop it down and take a picture of yourself holding it. Email the picture to firstname.lastname@example.org and I will pay you $1."
Then he hung the frame in the men's bathroom of one of the town's fast food restaurants. If the town didn't have a fast food restaurant, he lived in the town until it did.
