I believe everyone will have bookshelves with books and various objects on them. However, in this era when the Internet occupies most of the time, it seems that it has become very rare to take a book from the shelf to read. With kindle and various mobile phone apps, we can listen to books, read e-books, and get the world we want to know faster through various channels. Compared with bulky books, these methods seem more convenient and efficient, and for many people, they can stimulate reading interest. The bookshelf itself may be like being invisible, staying there quietly, sometimes disappearing, sometimes appearing. [The Lost Bookshelf] stems from the above thinking. The choice of transparent acrylic material and the gradual effect of painting make the bookshelf gradually disappear.
