This diploma thesis deals with corporate identity of a tractor manufacturer. For this purpose fictive company called Haart was created. The endeavour of this corporate identity is to make an image of a reliable company which specialises in the production of high-quality agricultural machines. This is accomplished by an orange-grey colour scheme where orange stands for living (agricultural production) and grey refers to lifeless (tractor is a machine). The final corporate identity is presented next to company stationery, merchandise, orientation graphics and web page also on the tractor designed within the pre-diploma project. For advertising graphics needs typeface Haart was created. Part of this diploma project is also the creation of a design manual. It describes all elements of Haart‘s corporate identity.
