This is how it looks in 99% of Czech Republic.
It changes to terrain signs painted on trees sometimes but it is also standard. I found 2 other signs for cyclists, some cross border route that decided to make their own on both sides. And still most cross border routes use cz standard signage.
So how it looks where you live? Am I just too spoiled by standards for hiking and cycling signage?
Yeah the Czech system is pretty close:
