mini national association professional bb league ball
 

I just picked up a miniature ball that is is really great condition with red stitching. The printing is fairly faint but say National Association professional BB league and also has a faint signature of W.E. Bramham who was the president of the league from like 1932 to 1946. This ball is only about 2" across so am not sure what it's exact purpose was...ideas on that or value? Thanks
