two mosaic fish decorations affixed to a weathered brick wall. The larger fish, predominantly white and gray with blue fins, is positioned in the lower half of the frame. Its body is adorned with intricate mosaic patterns. Above and to the right, a smaller, more vibrantly colored fish, made of red, yellow, and black tesserae, is visible. The brick wall itself is constructed of reddish-brown bricks, some of which appear chipped and worn, with visible mortar. The setting is an outdoor environment, likely a street or courtyard in Saint Petersburg, Russia, indicated by the architectural style of the brickwork and the general urban aesthetic. No people are present in the image. The scene captures a detail of street art or decorative embellishment on an old building.
