No person shall publish or cause to be published in any newspaper or other periodical, either in its advertising or reading columns, any paid matter designed or tending to aid, injure, or defeat any candidate for public office or any question submitted to the voters, unless the name of the chairperson or secretary or the names of two (2) officers of the political or other organization inserting the paid matter, or the name of some voter who is responsible for it, with that person’s residence and the street and number, if any, appear in the paid matter in the nature of a signature. The matter inserted in reading columns shall be preceded by or followed by the word “advertisement” in a separate line, in type not smaller than that of the body type of the newspaper or other periodical.
