Billboard Hall of Fame: Martor Razor Blades.

(click image) Everybody loves a billboard! They're big, and cause untold, unproven driving fatalities. Here, from 2007, is a classic—though I wonder how many fake dead pigeons the agency had at the ready to keep replacing the stolen ones. Ad agency: Venividi, Germany. Previously in Billboard Hall of Fame:
• Mars.
• Kill Bill.
• Hot Wheels.
• HBO's Hung.
• Science World.
