Lineup Card Experts - Need Help, Please.

[aphanna25]

This is a long shot, but I occasionally see for sale on here (and EBay), the official lineup cards from MLB games played long ago. I am looking for one specifically, June 14,1989, DET @ BOS, either the one given to the ump or posted in the dugout. I am not a scorecard collector, and many folks around here seem to be quite resourceful, so any advice on how I should even begin to look for this? Admittedly, I do not know the life cycle on how these come to market, whether the team releases them from archives or perhaps the umpires hang onto them and dispose/save/sell off etc. I know of one seller who had some 1989 Red Sox cards, and he got them from a former umpire who sold off an old filing cabinet full of them. I've thought of reaching out to the Red Sox, and even Ken Kaiser (the plate umpire on that night), but realistically I'm not expecting much. Anyone have an idea, or know a seller who perhaps has that market cornered and may have this amongst his thousands?

Thanks everyone.
