Where to find stats for each decade/ League?

Howdy,

Where does one find stats for each league/ decade (i.e., Back to the 80s, That 70s game, et al.)

Go to the 2012 player salaries pool and then click on where it says, player sets, then you can choose from 70s, 80s, 90s etc. But you might need to either have had a team in the past, or buy a credit to see the whole player set, I am not sure about that part. I hope someone else can give you a more definitive answer. Good luck! Get in on the 1970s Mystery League, still four spots to go.
