The term “comic” is used to refer to a strip or sequence of cartoons/vignettes with or without text that tell a story (however short it might be) in which at least one character appears in more than one vignette. The comic is recognised as the ninth art form, and there are a great variety of types and names, depending on the source and the format: historieta, tebeo, manga, bande dessinée, banda desenhado, fumetti or comic-book, amongst others. Virtually every country has its own characters and collections, and those that deal with universal subject matter or historical questions transcend frontiers and gradually become known the world over, the following being such examples: Tintin, Asterix, Mortadelo and Filemón, Corto Maltés, Superman, Spiderman or Flash Gordon, which have now become real classics. Comics undoubtedly have the ability to convey knowledge and feelings. Their educational value enables children and adults alike to gain insight into different areas of reality, in the past and present, dealing with almost every aspect of life: nature, mankind, technology, legends, cultures, history, adventures, etc., allowing the reader to explore the boundaries between fiction and reality, even heralding a future that can prove to be most unexpected and surprising. Comics make learning easier and stimulate the imagination, and they are an excellent resource for developing creative thinking and artistic sensitivity, while at the same time encouraging the reader to adopt a critical stance. They can be suitable instruments for creatively and intelligently explaining the world of ports and the sea, and to make this accessible to all types of potential reader. This is particularly the case where the port landscape is concerned, because of the nature of the artistic discipline that is deeply rooted in the way cartoons or vignettes are illustrated.
