they'll have fun when the bread finally disintegrates into nothingness and what a waste of money that'll be- woohoo i payed a freakish amount for something that has rotted away and doesn't exist anymore!
there was actually an artwork like that, i can't remember who, but they made this work out of orange peels that had been sewn back together- heaps of them all on the floor, and some art gallery bought it. and then naturally the orange peel began to rot, and so the gallery was left with nothing and they got really angry about it, having to pay however much for a work that just disappeared on them
