Vintage theater stage with spotlight on stand microphone

Design a vintage postcard featuring an empty theatrical stage with deep red velvet curtains and golden tassels. A single vintage stand microphone is illuminated by a dramatic warm spotlight at the center of the wooden floor. In the softly lit background, empty choir risers and scattered sheet music stands are visible, evoking a nostalgic atmosphere. A small bouquet of crimson roses rests on the stage edge. The composition includes a large ornate empty golden frame or banner at the top center, specifically left blank for adding handwritten text later. Artistic style: romantic, dramatic, nostalgic oil painting, warm sepia and crimson tones, classic 1970s theater aesthetic, cinematic lighting. Postcard format, portrait orientation.
