I have created a book cover series for 5 utopic books as my school project.
Most of the time I was doing a research to find the ideal books which will have much in common, despite they were written by various authors or in different time period.
I've choosen the ones you can see below. All of them are about utopic, decadent visions of the world.
I was working with the symbol of an eye, that has a significant role in every book. Needless to say, the eye itself attracts the human's attention very well.
Please note that penguin sign is just for the illustration (it worked for me in the whole design) of book series logotype placement and I never had any intention to misuse it, as it was realised only as a school project.
