Why are the antlers on a deer crossing sign backwards?

As "The Straight Dope" once noted, the sign is a just a silhouette, "so if the deer had antlers that maybe curved around the head ... wouldn't they show up as backwards on a sign?" They looked into it and determined the silhouette is of the common white-tailed deer, and photos show the antlers do indeed "thrust forward."
