If you enjoy science and especially biology, then this notebook is perfect to be your diary or journal. Its cover displays vintage illustrations by Ernst Haeckel, a German biologist, scientist and artist who discovered thousands of new species. The artwork comes from his book "Art forms of Nature" and even though there are flaws or even smudges on some of the illustrations, they are still beautiful and these imperfections just add a certain vintage charm. This is the perfect gift for any scientist, marine biologist and animal lover.
