Advertisments featuring comics-related graphemes like onomatopaea or word balloons are quite common. These two ads, for Orion sound and pollution proof windows, represent a rarer kind, though. They use symbolia, to use Mort Walker’s term, to add meaning to an otherwise static representation of the facts : speed lines and fire represent noise; a puff of smoke suggest movement and dirt. Simple, but effective.
