Two sumo wrestlers of Japanese descent, dressed in traditional mawashi, are featured at the center. They are engaged in a friendly match atop a pastel-toned birthday cake. The sumo wrestlers exude mighty power yet their stances are poised in a playful manner to reflect the light-hearted occasion. Above the scene is a banner showcasing a proclamation of 'Happy Birthday' in bold, whimsical letters.
