Graphics, Illustration and Visual Communication Design Auer Signal Corporate Design by Georg Illy Auer Signal is one of the biggest producers of high-quality signalling equipment. The former design did not reflect this quality. So a minimalistic visual language with a new Logo, high-quality photography, a new website and printed selling material were created. The history of Auer Signal were also an important aspect at the development of the new visual identity. The company exists since 1910. The Logo Mark for example is inspired by a fan, an old product of Auer Signal.
