a plain two dimensional generic pair of football helmets clashing head-to-head, featuring basic helmet domes with subtle solid fills, distinct ear cuts, and simple facemasks facing each other in the style of an app icon with very thick line weights and a very simple design

The image shows three football helmets outlined in black against a white background. The helmets are arranged in a triangular formation, with the largest helmet in the center and two smaller helmets on either side. The colors of the helmets range from black to white, creating a stark contrast against the white background, making them stand out.
