Bus Advertising

Occasionally, the entire surface of a bus is turned into an advertisement. This can be a whole side or rear of a bus, or a scheme applied to the entire exterior, known as an 'all-over advert' bus.

Some panel and full side and all-over adverts were traditionally painted on if the length of application warranted it. This would require a reasonable longevity and cost implication for advertisers, due to the requirement to take buses out of service to apply and remove paint schemes. Frequently changed panel adverts would use replaceable boards.
