Introduction of works: This collection of books is from the hands of Danish artist Otto Larsen, depicting a forest landscape in an expressionist manner. There is an Esperanto inscription on the top of the book: Tra densa mallumo brileras la celo (in the dark, there is still glory). About the book collection, Jomo originated in the fifteenth century. Because the books were not popular at the time and the cost was high, most of the books that could be read were the church monks and nobles. In order to express the ownership of the books, they were printed with prints (mostly woodcuts at the time). The owner's badge, marked with the Latin word EX-LIBRIS, is attached to the butterfly page of the book, indicating that "this book is for me." Subsequent printing became more popular, book printing increased, and the tradition of collecting books remained. In the 19th century, with the help of many artists and collectors, the book collection became a unique art department. Due to its small size, it is often referred to as a gemstone on paper. Book collection is a kind of ownership label, which also shows the collector's own preferences and tastes. The artist also developed a rich theme for the collection of books.
