The headlines and continuous texts were arranged typographically. The illustrations were developed to underline the text content. The whole thing was implemented in the material aesthetics of chalk, on anthracite-coloured walls, with the requirement that the chalk elements also had to be durable. As the visitors of a trade fair are confronted with many digital and printed displays, these types of hand-drawn illustrations are an alternative that  attracts attention and fascinates business people who pass by.
