Mine's nothing like some of these very impressive rooms, but it's coming along.
One wall is dedicated to Negro League autographs, most of which I obtained in person:
Then the main wall of the loft, the baseballs share it with the TV. For now.
A closer view of the displays to the left of the TV. The stand on the left is mostly major league balls with some minor league special even balls thrown in, the one on the right is regular season minor league and international league balls.
