The San Francisco Wasps were a former independent minor league baseball team based in San Francisco, California. They were established in 1901 and played in the California League. 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% 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. We print & ship all of our high quality graphic tees in the USA.
