Abstract: A banner apparatus comprising a base having a substantially symmetrical central core formed in an upper end of the base and a banner-insert sub-assembly removably installed within the core from either open end. The core has a substantially symmetrical and central stepped inner surface that is accessible from each open end. The banner-insert sub-assembly comprises an insert having at least one passage therethrough and a windsock banner installed over the insert so as to be pinched between the insert and the core when the banner-insert sub-assembly is removably installed within the core during use, the banner having a proximal end and a distal end and at least one airflow channel in communication therebetween and with the passage and the core so as to allow airflow through the base and the banner to aid its substantially horizontal flight during use.
