On the occasion of Empoli's centenary, a celebratory publication by Geo Edizioni could not be missing, which in the past has already published three volumes on the Italian club. “Shivers of Blue” traces year by year the history of the jersey of this provincial club which in its history has played a total of 24 championships between Serie A and Serie B.
 Over one hundred and fifty color images document from the foundation the official uniform of the Tuscan team and then also the second and third game outfits. There is also a chapter dedicated to the various stadiums and the study carried out on the period from 1980 to the present day with the evolution and subsequent intertwining of football uniforms with sponsors and marketing is very interesting.
