For my Graphic Design 2 class, we were to design a book cover with at least 3 symbols.
The Old Man and the Sea's main theme is the battle between tradition & culture versus new technologies and advancements (in this case fishing tools in particular.) This battle is represented in the literal sense between the marlin and Santiago, the old man.
To show this battle I constructed a marlin out of traditional tools.
To symbolize culture I made the background the Cuban flag, Santiago's home country.
Lastly, I blended Santaigo's beard into the sea to show the battle but also how he was almost one with the sea while alone in his fishing boat for months on end.
