The concept: In order to show the maturity and visually express many years of experience that Grimaldi Lines has. I chose to draw a tree rings, which is a visual connotation to maturity of the company during all these years. Tree rings symbolize trustworthy and brings respect. As well rings may refer to the connection of the worldwide net/ collaboration/ concentration. As the poster is for Grimaldi lines port of Barcelona I am using the shape of Barcelona map.
