I wanted these cards the first time I laid eyes on them. I picked these up on eBay. Supposedly, you can get them from select police stations in Wisconsin but I tried a couple without any luck. These are series 1, with the text on back that come in a wax pack. There seems to be a series 2 that is sold in plastic rip packs with blank card backs. I believe there are color differences on the front of the cards between the 2 series as well (e.g. Contreras has a blue background).
