The Brooklyn Atlantics were an old school baseball club originally established in 1855. This design commemorates their first year in the National Association (1872), the year they joined the professional circuit. This design is part of our old school retro baseball designs inspired by the vintage and now defunct Minor League Baseball teams of yesteryear. Printed on our super soft 3/4 sleeve baseball style raglan T-Shirt. We print & ship all of our high quality graphic tees in the USA.
