On the top of the poster there are informations about the projectual aspect of the book as who did the cover, who has designed the whole book, the editor, the manager, which edition is this one, rights and so on. To distinguish italian version from the english one, I used black for the italian text and purple for the english one, chosing these colors starting from the cover of the book. 

The bottom of the poster presents informations about the phisical aspect of the book like paper, legature, size, cover and so on. As i did for informations on the top i used black for the italian text and purple for the english one, chosing these colors starting from the cover of the book. 

As in the novel of Borges, the exagon which represents the container of books, is used to contain all the posters from Fifties to Eighties. The exagons, each one symbolize every decade, are overlapped like a pyramid or a tower, seen from above, to exalt the different graphics kind of design used through the  years. The bigger exagon represents the Fifties, then the small one stands for Eighties.
