public event in what appears to be a town square or public space. A small crowd of people, including adults and children, stand watching a procession. Several individuals dressed in traditional Bulgarian costumes are dancing, and there are also people in sheepskin costumes wearing ornate masks. One individual is wearing a Santa hat over their traditional attire. In the background, there's a building with a banner that says "Честит Празник, Айдемй." There are also balloons in the colors of the Bulgarian flag. The weather appears to be overcast and cold.
