Since 1993 the Packers have partnered with local Wisconsin Police departments to put out a Packers Police set. Since 1990 the set was standardized to 20 cards per set and the cards are usually released in groups of 4 per week for 5 weeks, I'm not sure how they are distributed. But you can usually find complete sets pretty easily. I found this set on ebay for cheap and added it to my collection of Police sets. The only player I think that was missing this year from the set was Jordy Nelson, but with his year this year I'm sure he'll make the cut in next years set. Enjoy.
