Anon previously said there are 47 of them in the pic. I'm thinking 53-47, as I am sure many of you are. So Occam's Razor here. What do we know at a simple glance?
It is a fence/wall/barrier.
There are steel slats.
They are pikes. (47 heads on pikes? Figuratively/Literally?)
47 up high, standing tall? (Comey-code phrase)
There are three in a circle, in the detail shown.
Three are special, or these particular 3 are special, or worthy of note. They are 21, 22, 23.
Is this a countdown?
The P@in comes in 23? 1, 2, 3? Mirror, 3, 2, 1…P@in?
Pic in >>4415277 enlarged looks like an ink stylus of a pen.

Just some thoughts. I don't have a conclusion. Just spitballing the simplest denominators that can be concluded.
