The intaglio 32 may also be translucent or transparent, and if necessary, various colors may be painted on the face of the intaglio 32. The intaglio 32 may be a character, a figure, a picture, a picture, or the like.

A light emitting diode is built in the pedestal 10, and the light emitted from the light emitting diode hits the intaglio 32 through the display 30, which is transparent or translucent. To reach the line of sight.

Power supplied to the light emitting diode module (not shown) has been omitted. The power source may be a 220V home power source provided by KEPCO, or may be implemented by a car DC or a battery or a rechargeable battery.
