An apparatus for displaying a flag, banner, or pennant, so as to simulate waving in wind, is particularly adapted for use with a novelty flag that is scaled for use in model railroad layouts. The apparatus employs a correspondingly scaled flag staff for coupling with and supporting the flag along one edge thereof. A drive arrangement is coupled to the flag staff at the base thereof for producing a rotatory oscillating motion. Electrical energy for the drive arrangement, which includes a small electric motor having a motor shaft with an eccentric element attached thereto, is provided from a conventional energy source, such as batteries. Coupling between the flag staff and the drive arrangement is achieved via a mechanical energy storage device that includes a resilient spring arranged to receive mechanical energy from the drive arrangement. The eccentric element attached to the motor shaft includes a mechanical striker that is in the form of a spring wire wound about the motor shaft. Mechanical energy stored in the mechanical energy storage device is delivered to the flag staff via a drive coupler that is coupled to the mechanical energy storage arrangement. The mechanical energy received by the mechanical energy storage arrangement is converted to the rotational oscillatory motion of the flag staff, the rotational oscillations being of such frequency and amplitude to induce an undulation in the novelty flag, whereby the flag is raised from its draped orientation so as to extend outwardly, giving the appearance of being supported by the wind.
