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 super soft ring-spun & combed cotton unisex T-Shirt. Or upgrade to our Luxury vintage heather edition (cotton/poly blend) for an even softer, more durable, classic look. We print & ship all of our high quality graphic tees in the USA.
