The San Francisco Pirates were an old school minor league baseball team based in San Francisco, California that played in the Pacific National League. They were established in 1903. This design is part of our old school retro baseball tees inspired by the vintage and defunct, forgotten and obscure Minor League Baseball teams of yesteryear. Featuring original designs, re-imagined from scratch. 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.
