"election advertising" means any poster, banner, notice, circular, handbill, illustration, article, advertisement or other material that can reasonably be regarded as intended —
(a) to promote or procure the electoral success at any election for one or more identifiable political parties, candidates or groups of candidates; or
(b) to otherwise enhance the standing of any such political parties, candidates or groups of candidates with the electorate in connection with any election,
and such material shall be election advertising even though it can reasonably be regarded as intended to achieve any other purpose as well and even though it does not expressly mention the name of any political party or candidate, but excludes any button, badge, pen, pencil, balloon and any other thing prescribed by the Minister by notification in the Gazette;
