This image depicts a classroom scene, likely within a school in Nova Zagora, Bulgaria. The central subject is a detailed model of an antique cannon, constructed primarily from wood or materials simulating wood, featuring large spoked wheels and a sturdy carriage. The model rests on a light-colored rectangular base, which is placed on a light-grey classroom desk in the mid-ground. Seven individuals, appearing to be students, are present. In the left foreground, a male student with glasses and a dark shirt is seated, leaning forward and writing or drawing on a paper with a pen. He has a blue hood over his head. Behind the cannon model, a group of six students is gathered around a light-grey desk. Four female students are standing: one in a white long-sleeved shirt and glasses leans forward; another in a grey top has both hands raised to her head; a third stands behind them; and a fourth, with lighter hair, is further back. Two male students are also visible within this group, one in a black hoodie and another in a black t-shirt, observing the scene. The classroom features light-green walls adorned with various educational posters, including a green chart on the left, an icon-like image of a saint, multiple smaller documents, and a diagram of a tree. A whiteboard with writing and diagrams is mounted on the far right wall. The room contains rows of light-grey desks with black-framed chairs. In the immediate foreground, a black puffer jacket is draped over a chair to the left, and another black puffer jacket is on a chair to the right. A black handbag with metallic accents and a small fluffy keychain rests on the desk in the foreground to the right.
