relief sculpture on a concrete wall

relief sculpture on a concrete wall. The sculpture depicts several figures in historical clothing. The leftmost figure is a man with a beard, wearing a fur hat and holding a pipe or a similar object. Next to him is another man in a coat and hat, holding a staff. To his right is a seated figure in a wig and coat, holding a document and a quill. Further to the right are more figures, one holding a staff and another group of figures clustered together. The sculpture is set against a backdrop of rocky textures and is partially illuminated by sunlight, casting shadows. In the background, a black metal railing runs along the top of the wall, and a tall white structure is visible against a blue sky with white clouds. The foreground consists of green grass.
