How can I purchase a Packer stock?

here is what I found out about this "stock"

'Packers’ stock is very different than the shares of most public companies. There’s no ticker symbol, it doesn’t trade on any exchange and shareholders don’t receive a dividend. What’s even more unusual: You can only buy Packers stock when the team wants to sell it, and you can only sell the stock back to the team. And the Packers have offered stock for sale only four times in their history: in 1923, 1935, 1950 and 1997. The 1997 sale, which priced shares at $200, raised more than $24 million and added 105,989 new shareholders."

It really doesn't seem like much of an investment to me, though I suppose you have the privilege of owning a piece of the Green Bay team
