Such sample ballots shall be printed on paper different in color from the official general election ballot, and have the following words printed in large type at the top: "This ballot cannot be voted. It is a sample copy of the official general election ballot used on election day." The sample ballot shall also state clearly the days, hours and places at which early voting shall be available in the county.
