In this book, Fr. Riba is paid tribute by numerous visitors who, at the end of their visit to the Salt Museum, left a record of their impressions with enthusiastic mentions of the objects and the person who made it possible to see them.
Bishops, ministers, governors, famous artists and a long list of visitors issued high praise for the collection.
In this book, however, there is a page of note: the one shown to visitors that allows them to admire the extraordinary technique and skill of the sculptor Lluís Vermell, who drew on it his self-portrait and the portrait of his friend Fr. Riba.
