There are books "that can not wait" Bashny.Net

Argentine publishing Eterna Cadencia came up with the original concept of promoting young writers. It uses a disappearing ink that disappears after two months.

This format publishing house was named El Libro Que Puede Esperar, which means "book, which can not wait." Usually people do not rush to read the book first thing in the young, new authors, preferring the works signed by familiar names. An intriguing book starts as a writer comes in a plastic case. Once it is removed, the book begins the countdown and after 60 days the reader will see only a lot of blank pages.

So if the buyer really wants to get the book for my money, he should start reading immediately. In addition, such a simple way is achieved while maintaining the copyrights.

The first batch of books with disappearing ink were sold on the first day. Publisher, impression of success, intends to continue the publication of books with unusual ink.
