note:
Knock, Knock Poster is another reproduction of a drawing used for an exhibition poster. In this instance, the onomatopoeic text, “Knock Knock” is employed as a vital component of the composition. This playful treatment of language has further whimsical significance in that it acts as a pun on the publisher and exhibition venue’s initials, ‘CNAC.’ Here, Lichtenstein contributes to a long history of witty word play in visual art ranging from Duchamp’s infamous, “L.H.O.O.Q” to present day, living artists’ work such as Ed Ruscha’s “HONK,” and “OOF”.
