Window decals: Window decals are sticky images that attach to your windows and let light through but display an image to the outside. This means that you can essentially place advertising on your windows and this is highly useful when you consider that it allows you to use up a large part of your building that is not being used. When you put an advert on a billboard you will pay lots for it – so why not use your window as your own billboard? And as the image is actually inside when you use window decals you know it won't get damaged or get you into trouble.

Vehicle decals: Vehicle decals attach to the side of vehicles instead of to windows. This again uses what is essentially a blank canvas for promoting your company, but it also has other advantages that set it apart from other strategies – not least the fact that it lets you have an advert that travels across the whole country or even internationally.
