Two males are depicted indoors in a close-up, likely self-taken photograph. In the foreground on the left, a young child with short brown hair and a blue long-sleeved shirt with red lettering is shown with his mouth wide open in a scream, his eyes squinted shut. His right arm is flexed, with the hand forming a fist near his shoulder. Behind him and to the right, an older adolescent male with dark brown hair is partially visible. He has his right hand raised, forming a "rock on" gesture with his index and pinky fingers extended. His expression is a slight smirk, with his tongue subtly visible past his lips. The background features a plain light-colored wall on the left and a darker wall with a patterned, possibly floral or damask, wallpaper on the right. No specific location within the city of Sofia, Bulgaria, is discernible from the provided visual information.
