The Waterloo Hawks were a minor league team that existed on-and-off from 1922 to 1969. They were affiliated with the Chicago White Sox, Boston Red Sox and Kansas City Royals. This design is part of our old school retro baseball tees inspired by the vintage and defunct Minor League Baseball teams of yesteryear. Printed on our super soft 100% ringspun & combed cotton women's T-Shirt. Or upgrade to our Luxury 52/48 cotton/poly vintage heather edition for an even softer classic look.
