Instead of the frame holding the ad flat as is typical, the ad is billowing out of the frame. Two corners are hanging free at the top, so the whole ad poster is leaning towards me like \ instead of lying flat like |. That’s atypical. Part of me says it was pulled out by some unruly passenger (perhaps a child) or just wear and tear of the frame. A small part is not sure if it is a guerrilla marketing campaign to draw my attention to the advertisement.
