I was able to design covers for a series of books titled "Utracony Świat" (eng. lost world). The order also included the preparation of seven black and white illustrations. Books available in Polish.
Full cover design of the first volume of the novel.
Full cover design for the second volume of the novel.
The illustrations for the covers show the main character of the novel.
Set of illustrations for both books. The first four are included in the first volume of the book, and you will see another three in the second volume.
