A mobile billboard was created comprising of a bike and a trailer with an illuminated billboard. The power for illuminating the billboard was generated by pushing round the bicycle pedals – 100% environmentally friendly. The Ökopool advertising salesman rode with this mobile illuminated billboard to all the country's major media agencies.
