Who is this African American player?
 

From 1907-1909, George Wilson (ex-Page Fence Giants) played with Manitowoc. A 1907 postcard that includes George, seated, is at the bottom. Above it is a Manitowoc team postcard with a 1913 postmark that includes a standing African American player (I've sharpened the image with Photoshop because my scanner muddies it). Anyone recognize the player? Any info to share? Thanks.

Perhaps Native American. Just throwing out another possibility.
