I was there last year........you waited in line for whoever you wanted the autograph from. Now, they would change who was signing every couple hours, so, sometimes you got in line for a player, and he would be gone before you got to the front of the line. I spent probably 85% of my time the 3 days waiting in line. The autographs are free, but you have to provide what you want signed. (You can buy stuff at the Packer Pro shop, but it's expensive there)
For the star players (like Bart Starr) you have to be lucky enough to get the VIP pass when you come in the door that day. (They give you a card with a sticker covering part of it, you peel off the sticker to see what you get that day) If it says "Bart Star" you will get to get his signature that day. Me, all i got the 3 days was "15% off purchase at Pro Shop". I didn't get ANY star players (they had Starr, Favre, Paul Hornung, Jerry Kramer, and Robert Ferguson last year)
But i did get good sigs. Like Gilbert Brown, Grady Jackson, KGB, Nick Barnett, and so on.
Now, i'm not certain they will do it exactly the same this year. I gave them my opinion, and said they should have like 3 players at a table, so if you wait in line for 3 hours you get more then ONE autograph. I hope for those that get to go this year, they do it that way.
If you have any other questions, i will try to answer them for you.
