Aniko Kolesnikova is a Latvian artist who recently got her share of Internet fame for her incredible work with book covers. She creates polymer journals inspired by nature and all kinds of fantasy animals.
Doing so, she perpetuates a long tradition of book binding and decoration from Europe. Her books look like they come straight out of the Middle Age or a fantasy land. You can buy some of her covers on Etsy or just view more on her website Mandarin Duck. She even has a Youtube channel where she shares excellent tutorials.
