Big Head Who?

So I’m checking out what’s going on at some local blogs and I found this post. I had no idea something this strange was in Houston. J needs a picture of herself with giant severed Reagan-head.

I’ve never quite understood the giant severed head school of sculpture. I can understand the life-sized bust or the larger-than-life full statue. However, a giant head of a size to frighten small impressionable children always struck me as odd. Why just the head? The whole idea smacks of weird pagan trophy taking and setting heads on pikes.
