The grin that buries the brand

Every morning on my way to work I pass by a realty brand's billboard that features a facial profile picture an ex-Mayor of some unheard of place in London. On the billboard the guy's grinning broadly vouching for the property being peddled. I have rarely missed the billboard, but the only thing notice almost every time, is the crooked-toothed grin that splits the mayor's face into two.

Horizontally.

I wonder if the guy knows he has crooked teeth, and if he does, why is that he keeps his mouth open when a picture's taken? Plus I can't for the life of me either remember the real estate company in question or the project being peddled.

So much for marketing communication, eh?
