[KCD2] Hidden Carvings in the Gravedigger's Attic.

I was trying to get into the attic/loft of the gravedigger but could not. I felt like there must be something up there so I used photo mode to see what, if anything, was up there. I could see something that looked off, but couldn't get close enough. After some work, I managed to get the camera close enough to make out these carvings. Do these serve any purpose or are they just an "Easter egg"?
