Whenever a political party committee makes an expenditure for the purpose of a communication through Internet advertising, direct mail, magazine advertisement, newspaper advertisement or any other printed medium, the communication shall state in writing of sufficient size and contrast to be clearly readable by the recipient of the communication: "Authorized and paid for by NAME OF POLITICAL PARTY COMMITTEE". This provision shall not apply to bumper stickers, campaign buttons, t-shirts, aerial advertising or similar advertisements of such a nature that inclusion of a disclaimer would be impractical.
