The image shows a round manhole cover on a concrete surface. The cover is made of metal and has a circular shape with a hole in the center. The word "GAZ" is written in bold letters at the top, followed by "C250 EN124" in smaller letters. Below the word, there are several colorful lines and shapes in different colors, including red, blue, yellow, green, and orange. The lines are arranged in a grid-like pattern, with some overlapping each other. There are also two small holes on the cover, which appear to be for drainage pipes or drains. The overall design of the cover is colorful and vibrant.
