An indoor image depicts a vertical mosaic panel mounted on a wall within the Chkalovskaya Metro Station in Moscow, Russia. The mosaic features two stylized birds, appearing as swallows or gulls, rendered in tesserae of white, light blue, and grey, depicted in flight against a dark blue and grey background. The mosaic's upper left section displays two curved, warm-toned arcs in orange, red, and yellow. The lower section of the mosaic shows horizontal wavy bands of dark blue and grey. The wall supporting the mosaic consists of a rough, light-colored plastered upper portion and a lower section clad with polished, light beige-to-grey stone tiles. Above the wall, two prominent, light-grey structural beams or arches are visible. A metallic Cyrillic letter "Я" is partially visible on the tiled wall in the lower left foreground. No individuals or dynamic actions are depicted.
