This lettering is for a Catholic Church just a few miles away in Poteet, TX. I always love the black metal contrasting against the white limestone.
A side note, when mounting letters like this you, need to be cautious of how the shadows between the metal letters and white rock might affect your ability to read the letters at a distance. The best way to fix this is mount the letters close to the rock or whatever your mounting them to so that a shadow can't get behind the letters very easily. Looks like the installer did a good job on this install.
