If you've got a copy of the excellent Reasons To Be Cheerful: The Life And Work of Barney Bubbles, you'll recognise this t-shirt instantly as the 1964 design for 60s R&B band The Muleskinners. And it's now been reissued in t-shirt form in very limited numbers.
Barney Bubbles was a graphic artist, working within pop culture between the 60s and 80s, but best known for his album artwork for the likes of Hawkwind, Stiff Records, along with his role in the late 60s counter-culture.
