This is a very simple sign with no frills (they would get lost in the background anyway).
As you can see the front shows the well known "No BS" picture, whereas the back shows the warning that you are leaving the No-BS zone!
Just position it, turn it, scale it or lower it to suit your needs.
If you want to derive your own version: the front uses a square texture, the back also a square texture and the pole uses a 2:1 repeating texture
