Museums are supposedly the ultimate destination for the best art of our age, and while that may be an improvement on the homes of moneyed patrons of an earlier age, it is a phenomenon on which artists have reflected critically – and quirkily – throughout this century. MOMA has gathered a collection ranging from the conceptually challenging to the downright prankish, featuring luminaries such as Marcel Duchamp, Christian Boltanski, Claes Oldenburg and Hans Haacke, providing the museum with a thought-provoking mirror of its own function.
