The Riverside Rubes were a minor league baseball team based in Riverside, California. They played Class C ball in the Sunset League from 1947-1950 and were affiliated with the Pittsburgh Pirates. 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.
