Part of the A/A/F 'Cosmic Transmissions' series. Hand screen-printed and individually numbered limited edition of only 25 pieces.

Competition to keep Detroit’s engines cool in the 1960s was fierce. The bold slogan on this T-shirt – by oil company STP – reminds A/A/F creative director Guy Berryman of early Katharine Hammett tees, despite predating her work.

Cut from a heavy cotton jersey and garment-dyed for a soft feel, this style features a slightly longer sleeve and is designed for a relaxed fit.

Screen-printed graphics create a unique finish and are subject to variation from garment to garment. Each is handcrafted, so please allow 1-2 weeks for production and shipping.
