In 1933 the Italian Flying Armada visited Iceland enroute from Rome to Chicago. The three stamps on the sheet are Scott Numbers C12-14 which picture Christian X of Denmark, which governed Iceland until 1944. The stamps are surcharged for the postage on items mailed from Iceland to the United States via the Italian seaplanes. The sheet commemorates the 60th anniversary of the visit.
     The map of Europe in the background of the souvenir sheet is presented on a mercator projection. There is no indication of the year of publication of the map, or of anything significant about it, other than that it shows both Iceland and Italy.
