Demarcation Line Marker

My Border time goes back to 1964-66. One of my most treasured possessions from my time there is this copy of the Grenzpolizei poster that was posted on trees along the demarcation line. The ones in the woods were just the black/white drawing and not water-colored as this one is. Don't know when/if these were discontinued; so some of you who are younger may have never seen it.
