behind the broken window

I don't understand purposeful destruction. But I will capitalize on it! I've been watching a particular building that is near where I walk. There's been a big, old piece of plywood covering the blocks of windows for many years. It's looked like someone had been trying to pry it loose & finally succeeded & low & behold...... graffiti is behind it! There was natural light behind me which showed off the cement blocks nicely. It's at an old fish hatchery, so anyone's guess is good as to what the blocks were used for.
