The above photo is of a house near my office. It’s a bit blurry because I shot quickly as I was driving past. What caught my attention was the prominent initial “F” worked into the chimney masonry. In a post-mortgage fallout, post-“Flip this House” era, the idea of marking one’s house so indelibly seems quaint, almost laughable.
This is a very permanent mark. In many cases tan colored bricks are built into the chimney structure. Just about the only way to remove the initial is to tear down and rebuilt the chimney. Painting over it only partially obscures the letter, as the bricks that make up the initial are often of a different shape or orientation, so you can still see the outline.
