There are some pretty cool players in the set to choose from, including (but not limited to) the following...
Lave Cross (quality player that actually has an Old Judge card)
Ivy Wingo (later would become long time Reds catcher, 1919 Reds)
Jeff Tesreau (great mid-1910's pitcher for the Giants)
Fred Toney (also became a Giants hurler)
Hank Gowdy (long time MLB player/coach)
Juan Viola (early Cuban star)
Ted Breitenstein
Eugene DeMontreville
etc.
etc.
-Also as an extension of a Hall of Famer you could get the card of Hornsby in Series 3 as that is Rogers' brother, then just tell everyone it is Rogers Hornsby (who besides us will ever know the difference
)
