The Boston Blues were a minor league baseball team based in Boston, Massachusetts from 1886-1887. They were an independent team in the Massachusetts State Association League. This design is part of our old school retro baseball tees inspired by the vintage and now defunct Minor League Baseball teams of yesteryear. Printed on our super soft 100% airlume ring-spun & combed cotton long sleeve T-Shirt. Or upgrade to our Luxury 52/48 cotton/poly vintage heather edition for an even softer classic look. We print & ship all of our high quality graphic tees in the USA.
