Most window security bars are functional and unattractive, but not this colorful piece of art that guards a basement window in a downtown alley in Flagstaff, Arizona. Despite the graffiti that’s blemished it, the whimsical figures look characteristic of a children’s book illustration. By the way, there is a Flagstaff Art Walk on the first Friday of every month during which retailers stay open late in order to display various works of art. Tour maps are available.
