These cards were used in Italian national elections in 1929 and 1934 when Mussolini’s party was the only legally permitted party. Voters (at the time, only males who were trade union members, clergy, or soldiers) could only vote to approve or disapprove the list of deputies the Grand Council of Fascism had appointed. The officials would check that the card the voter chose was properly sealed, so the colors would probably immediately let them know which vote is being cast. And/or it was propaganda: voting for yes is patriotic, and no is… less patriotic.
