The New York Mutuals were an old school baseball club. They were originally established in 1857 (formed from firefighters of New York's Mutual Hook and Ladder Company Number One). This design commemorates their 1871 season, the year they joined the first professional baseball league, the National Association. This design is part of our old school retro baseball designs inspired by the vintage and now defunct Minor League Baseball teams of yesteryear. Original branding reimagined by m00nshot for the lost baseball teams of yesteryear for which mostly nothing exists. Printed on our warm & cozy heavyweight unisex sweatshirt. We print & ship all of our high quality graphic sweatshirts in the USA.
