Perhaps the coolest thing about the Heihachi Mishima billboard is that, it implies Heihachi Mishima bought a bunch of stuff just to show Heihachi Mishima face. Didn't even bother to advertise about Zaibatsu or the iron fist tournament, its Heihachi Mishima promoting Heihachi Mishima without even attaching a name, everyone just knows its Heihachi Mishima.
