Welcome to the Net54Baseball community, hope you will enjoy things here as much as I have for the past 8 years or so.
A couple of years back, I published a 275 page guide on the subject of Negro League Baseball Collectibles with over 1,000 photos and pricing info included. This only one of its kind reference tool might be a good beginning point for someone looking to start a like-minded collection.
If interested in picking up a copy, either e-mail me at:
vguerrerobb@yahoo.com or send me a private message through Net54Baseball.
Best of luck in your future collecting endeavors!
