This is an expressive architectural element in the Art Deco style - a sculptural image of a lion's head, carved in stone and integrated into the building's facade. The lion's head with an open mouth is presented in the center of a round medallion, which in turn is framed by decorative spiral curls and stylized leaves.
The detail demonstrates geometric forms and rhythmic lines characteristic of Art Deco: circular grooves around the lion's head create an effect of radiation or radiance, emphasizing the central position and significance of this element in the facade composition. The details of the animal's face are masterfully crafted - expressive eyes, folds in the skin, and especially the impressive open mouth, which possibly had a functional purpose, such as a drain spout or ventilation opening.
Such decorative elements were popular in architecture of the 1920s-30s and were often used on facades of public buildings, banks, or elite residential houses to give them monumentality and character. The light-colored stone creates an effective play of light and shadow, emphasizing the volume and expressiveness of the sculptural relief.
