Dan BrettaJason, I am almost certain without looking that Wisconsin's population was at least two to three times (maybe more)that of Nebraska in 1910 which is about the time that rppc's were at their heighth of popularity...that would account for the major reason there are more Wisconsin rppc's at any given time on ebay than for Nebraska.
Just the fact that that website exists tells me that there is a rich baseball history in Wisconsin....I especially like that Cooksville Cornhuskers team 
One of my biggest regrets was getting outsniped on a rppc of the Nebraska Indians team in some small Wisconsin town. I knew I should have gone after it much harder than I did...oh well.
