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 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.
