I have done a lot of work for a touring car company. Companies like those involve a lot of promotional material. Brochures, flyers, newspaper advertisements. Even lettering on the touring cars themselves was a concept I created.
A common item used for promotion in print. Flyers. The art is to effectively use the limited space available to give a good overview of information. Vortex Adventures wrote out a contest to design their new flyer and I couldnt resist entering. Since then I did several other versions of the flyer for different activities.
The basics of any company's image is their logo and accompanying business cards, letter paper, etc. Even in my main field of webdesign it often starts with a logo. When doing logo design I always work with vector graphics for optimal use at whatever size is needed.
