Rugby Jersey Toyota Verblitz Top League

This is an official, dedicated jersey from the Verblitz's Top League era.
I believe it's from the season the Top League ended, or perhaps the year before it ended.

I received this from an acquaintance, so I don't know who signed it or where the signatures are.
I decided to list it because I thought it would be better in the hands of someone who appreciates its value.
I was told it's an authentic jersey, not a replica.

I'm not very knowledgeable about rugby, so I'm not sure how much I can answer your questions, but I appreciate your understanding.
