Full Metal Wheelbarrow

David Hockney has apparently had a dig at other modern artists for not doing all the work on their pieces themselves

You'd think that a famous artist like him would be rather more clued up about the history of art and know that there's a long-standing tradition of artists using apprentices to fill in the boring bits of their work, especially in fresco painting, where the paint has to be applied before the plaster dries, so you really need more than one pair of hands involved.

Of course, if the nominal artist isn't doing any of the work himself, that's another matter.
