Before there was rock ‘n’ roll, there were the Sweathogs. This Welcome Back Tour 1975 design reimagines the lovable troublemakers from Welcome Back, Kotter as a band on tour—because let’s be real, Vinnie, Epstein, Horshack, and Boom Boom would’ve absolutely sold out arenas. A perfect retro throwback for fans of classic 70s television, vintage sitcom nostalgia, and anyone who still answers roll call with a legendary Ooh! Ooh! Printed on our super soft ring-spun & combed cotton unisex T-Shirt. Or upgrade to our Luxury vintage heather colors (cotton/poly blend) for an even softer, more durable, classic look. Which colors are luxury? We print & ship all of our high quality graphic tees in the USA.
