Architettura della basilica di S. Pietro in Vaticano Task 2 - Archived Posted on 11/10/202009/13/2021 Behind the bookcover I have found a sticker that says: “Libreria Gozzini Firenze”. After googling it I have found out that it is a still existing library in Florence. The library is specialiced in antiquarian books. Here is the website: https://www.gozzini.it/?lang=en In between two drawings there are empty pages so that the ink is not visible on the next drawing. However for textpages there is no such prevention available. This drawing here stood out of all the other drawings in the book. It is indeed the only drawing with humanbeeings in it. Other drawings may have instead angels or saints in it.
