THINK TANK (2019) is the last screenprint edition by Lars Arrhenius. The profile of a human head in front of a city landscape is not an anatomical model. The silhouette is made up of pictograms, signs and - for the first time used - emojis. The areas of the head differ in different colors and selected shapes. For example, yellow emojis form the area of the brain. In THINK TANK the human head is declared to a place of production and creation of new things, but at the same time represented as a construct of external and internal influences.
