Illustrate a majestic eagle embodying the role of a stern, authoritative policeman in the year 1810. The eagle, clad in a traditional blue uniform adorned with brass buttons and gold trim, stands tall and proud with a stern expression, exuding a sense of power and command. Its sharp, beady eyes keenly survey the surroundings, while its wings are folded neatly at its sides, ready to take flight at a moment's notice. The eagle's talons grip a polished wooden baton, a symbol of authority and justice in its clawed grasp. In the background, the cobblestone streets of a historic 19th-century city are bustling with horse-drawn carriages and pedestrians in period attire, adding an authentic touch to the scene. The eagle-policeman's presence commands respect and instills a sense of order and security in the bustling, bustling cityscape of the early 19th century.
