EX is a psychedelic art piece created by Martin Sharp in 1967. It is screenprint, printed in black, blue and pink ink from three stencils, on silver foil laminated paper. In his blog, King Kong and the Birdman, Michael Organ writes that “Max ‘the Birdman’ Ernst and SEX! (King Kong) – date from 1967 and reflect an in-depth knowledge of Dada and Surrealism, with special reference to German artist Max Ernst, alchemy and the themes of anarchy, desire and freedom of expression.”
