We created the character of a positive superhero - Makromen, a guide for children in moving around high-rise halls. Large Makromen (human-stand) greeted the children at the entrance. A special leaflet with an iconic graphic has been prepared showing how to move around the halls in a way that is understandable for young children. Those who got to know the leaflet received a sticker - the Makromen badge. At a later date a drawing contest was held for Makromen club members.
