Doubtful this means anything, leads anywhere, or is even of the slightest interest, but the names Jimerson and Printup
jumped out at us. Those families don't appear to register (at merely a cursory search) among the Cherokee communities
in North Carolina and Oklahoma, but they are significant names in the Iroquois / Six Nations communities throughout
New York State.
The Iroquois Indian Museum at Howes Cave NY [
http://www.iroquoismuseum.org/ ] in 2008 put together a nice exhibition
of photos and memorabilia pertinent to Native American baseball. You might want to contact them to see if they can provide
any additional information or insights regarding the team shown in the postcard. Six Nations ringers on a North Carolina
or Oklahoma Cherokee team?
