The image is a vintage advertisement for Diamond, a company that produces diamond-shaped bicycles. The background is blue and the word "Diamant" is written in red capital letters at the top. In the center of the image, there is a cartoon-like illustration of a man and a woman riding on a bicycle. The woman is wearing a yellow dress with white polka dots and a red bow in her hair, while the man is wearing an orange vest and a white shirt. They are both smiling and appear to be enjoying the ride.

On the left side of the illustration, there are two bicycles, one with a blue handlebar and the other with a white handlebar. The man is sitting on the handlebars and the woman is standing next to him. On the right side, the man has his arm around the woman's waist and is smiling at the camera. The bicycle has a white frame and a blue seat and handlebars. The text below the illustration reads "Niemacki kvalitetini kotac sa zakonom zastěcenom markom diamant" which translates to "Diamond" in English.
