Before the Brooklyn Dodgers became the Brooklyn Trolley Dodgers they were known as the Brooklyn Atlantics. The Atlantics played during baseball’s infancy at Washington Park baseball field, which use to be a 3rd Ave. and 3rd St. in Gowanus Brooklyn. (Some amazing old photos of the baseball field can be found on this site. And yes the old wall to the baseball field still stands.)
Recently a baseball card of the Brooklyn Atlantics was unearthed at a garage sale. This card is now up for sale at the Saco River Auction Co. in Maine on Feb 6th, 2013. The value of this card simply can’t be estimated because the only other card like this one is in the Library of Congress. Pretty nifty! Check out the authentication document here.
