The Dubuque Shamrocks were a minor league baseball team based in Dubuque, Iowa. They played in the Illinois-Indiana-Iowa League from 1903-1905 and played their home games at the Base Ball Grounds. 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 warm & cozy heavyweight unisex sweatshirt. We print & ship all of our high quality graphic sweatshirts in the USA.
