How Do You Sell This One on Ebay?

According to this story, a man claims that sometimes an image of Jesus appears on his truck. You can see the photo here (it is copyrighted, so I cannot post it on this blog), and notice that it looks pretty authentic.
According to the article, this occurs when the driver side window has condensation every morning. I'm confused--I thought it was supposed to be when the dew was on the roses. I wonder how he can make a buck off this on Ebay like the people who sell their toast slices which have Jesus' image cooked in.
