1970s The Who "Happy Jack" tee with Ralph Steadman art, made in the USA. White cotton knit, short sleeves, regular fit. I have not seen another one and do not expect to.
Pit to pit 21 in, length 27 in, measured flat. Tagged XL but measures like an L. Vintage sizing is not modern sizing, so trust the measurements and not the tag.
One small mark on the left sleeve, photographed.
