Not great photos, but here are a couple.
The spear is displayed on the wall behind my life-size Predator. It's a bit awkward to get a good photo of it. The first one was taken as I mounted it to the wall and before moving the Pred back into position.
I'm currently re-thinking the display of my Predator pieces. I need to wall mount my Pred 1 & 2 helmets and the cutting disc (when I finish painting it).
