A close-up image displays a section of human skin, light to medium brown in tone, observed in Tel Aviv, Israel. The skin exhibits a series of approximately seven faint, parallel, horizontal dark streaks or residue marks, consistent with residue transferred from the rubber wheels of luggage, such as a suitcase or trolley. No other subjects, objects, or environmental features are discernible within the frame. The focus is exclusively on the marked skin.
