"Champion Original Bloomer Girls Base Ball Club" indeed-as the address side of this postcard proclaims, with 28 Games won in 27 days.  The team "claimed" the Amateur Championship of the United States so that seals it! The edges are coming up on two sides and a stain can be seen at bottom, while the image of the team looks fairly well preserved. The reverse has a final result and date (Aug 4 1912) penciled in but is postally unused, with areas of foxing..
