Gamba Osaka signed uniforms. There are 13 of them. They're from a team a few years ago. Yasuhito Endo's signature is not included, but there are definitely 13 signatures. I'm not sure who they are, I don't remember exactly. Sorry. The team was from the Nishino era, with players like Yasuda, Bando, Hashimoto, Futagawa, and Fujigaya!
