Looking for contracts of Campanella, Newcombe, Bankhead etc.
 

I hope everyone is doing well.

I'm looking to find contracts from early integrators such as Campanella, Newcombe, Doby, Dan Bankhead, John Wright and others. Particularly looking for players' first Minor League or Major League contract. For players like Campanella and Newcombe who played in the Negro Leagues, I'd love to find Negro League contracts or Puerto Rico League contracts from before they made the Majors as well.

Would appreciate any pointers in the direction of any even if you don't have one. A few years back a post here lead me to eventually acquiring Campanella's 1946 Nashua Dodger's contract, so while I know it's a long shot, I definitely appreciate any help!

Thanks!
