This ad is promoting bicycles. It gives three pictures of people riding different bikes that the company sells. It also gives the address of two different places where you can get one. There isn't much in this ad other than the pictures, it's very brief with limited information about the bicycles but it's important because bicycles are very popular at that time and they provided a good means for transportation.
