My son sent me a screenshot of a Japanese only Super Famicom (Super Nintendo) game based off the Ashit No Joe game. He explained to me that this part in the game is based off when the main character Joe Yabuki (left) fought against Rikishi and Rikishi died. The two had a tremendous respect for each other too. He even told me that in Japan when the character Rikiishi died people held a real funeral for him and there was a famous poet there and everything.

Well, about the card itself it's pretty simple and I put my little trademark (like my son does) which is the striped top and bottom. I think I should make some more cards sometime.
