Abstract: A mobile advertising system includes a banner, a first banner anchor and a second banner anchor coupled to a vehicle. The banner is capable of being deployed by being connected at opposing ends to and suspended between the first and second banner anchors. The banner has first and second surfaces on which indicia are imprinted. Both the first and second banner surfaces are visible when the banner is deployed. An invoicing and tracking system may be included that computes an advertising charge based at least in part on a time period during which the banner is deployed and, optionally, a location of the vehicle.
