A stamp belonging to the thematic series “The excellences of the Italian cultural heritage” is dedicated to Corriere della Sera, on the 150th anniversary of its foundation. Printed by Istituto Poligrafico e Zecca dello Stato S.p.A., the stamp depicts a typographic matrix that is comprised of movable type plates. These plates transfer ink to paper, resulting in a proof that is useful for verifying the content and quality of the print. In the background appears the front page of the first issue of Corriere della Sera, founded in Milan in 1876 by Eugenio Torelli Viollier. At the center stands out the logo for the 150th anniversary.
