This is a baseball signed by all the members of the U.S. team at the 2004 Japan-U.S. Baseball Series. It was won in a lottery held at the end of a lecture by Kazuhisa Ishii in Urayasu City in November 2004. I was told that it was signed by everyone, including the manager, but it's uncertain if it truly includes everyone. It has been stored in a case since I won it, but as the years have passed, it has become stained as shown in the photos. I didn't spill anything on it, so the stains may have appeared over the years due to sweat from the players when they signed it. The lottery ticket should be somewhere in the house, but I can't find it. If I find it, I will attach it.
