So MoMA can turn Meret Oppenheim's fur teacup into an icon--and it's full of nude actual people right now!--but it shies away from revealing the little muffed and stuffed genitalia Marcel Duchamp attached to Couple of Laundress' Aprons, his 1959 potholder readymades?
Created in Paris after a [penis- and/or merkin-free] original purchased in New York, twenty sets of potholders were included in a deluxe edition of a Surrealism exhibition catalogue. Toutfait.com has the details--and the full frontal photos.
