A clear, double-walled glass mug, displaying "Luigi Ferrero" branding on its base, rests on a light brown wood-grain surface. The mug contains a dark liquid, consistent with coffee or espresso, topped by a light brown crema layer. Residue or condensation is visible on the inner glass surface above the liquid level. A clear glass handle extends from the left side of the mug. In the background, an arched doorway opens into a brightly illuminated space featuring a window with light-colored, semi-transparent curtains. A light-colored, vertically ribbed surface is partially visible on the far left background. The scene is an interior setting in the city of Byala Slatina, Bulgaria.
