collection of four weathered circular signs mounted on a white pole against a pale blue sky

collection of four weathered circular signs mounted on a white pole against a pale blue sky. The top left sign is white with a red border. It displays the number "15" in large black font, with the letter "M" below it. Two black triangles point inwards from the left and right sides of the number "15". This sign indicates a maximum speed limit or a measurement. The top right sign is similar in design, white with a red border. It shows "4,5" in black numbers, with a comma separating the digits, and "M" below. A black triangle points downwards from the top of the sign, and another points upwards below the "M". This sign likely indicates a maximum height restriction of 4.5 meters. The bottom left sign is also white with a red border and features a large black numeral "5". This sign probably represents a speed limit of 5. The bottom right sign is highly damaged, with a white surface covered in a network of fine cracks and peeling paint. It has a red diagonal stripe across it and a symbol of a lit cigarette with smoke, also crossed out by the red stripe. This is a "No Smoking" sign. The signs are old and show signs of rust and wear, particularly around the edges and on the surfaces. The sky is clear and slightly overcast. In the background, a street light can be seen. The context suggests these are traffic or regulatory signs, possibly located in an area with restrictions on vehicle height and speed, and a prohibition on smoking. The image is framed from a low angle, looking up at the signs.
