Well I have a very foolish idea. Let me preface this by letting you know that I comprehend the fact it's a silly, harebrained idea. I get it. I know.
However...yesterday when I was sharpening BG's head and facial area, something struck me as odd. I actually kept seeing this sort of animal face on his head. I saw it from time to time a few weeks ago also. It comes as goes. But we have to remember that when distorting, zooming, sharpening photos we often see things. So that's probably the case here.
But I'll go with this off the wall idea: What if BG is wearing an animal skin hat? I'll upload some examples. There are several taxidermies not far from Delphi and he could have also made it on his own.
It's just a crazy idea! Sort of like the puppy poking out from the top of his jacket.
You have to enlarge my rough drawing in the photo.
