ABSTRACT:
A flag assembly has a pedestal frame which contains a miniature phonograph recorder that is battery operated and which has two contacts that are connectable together to activate the recorder. One contact is connected to the conductive base of a flag staff and the other contact is connected to a flexible flap which can be bent into engagement with the base to activate the recorder. A shuttle having a sleeve and a flange is slidable along the staff. In its lower position the flange presses the flexible flap against the base to activate the recorder. A flag is engaged around the sleeve. A rope has one end connected to the sleeve at an opposite end engaged around a pulley at the top of the staff and extending downwardly into the pedestal frame. A spring-loaded spool in the pedestal frame is connected to the opposite ends of the rope for winding and unwinding the rope.
