The latest threat to the art world appears to be art enthusiasts armed with sketch pads. This week, a Canadian man was told to stop sketching an ancient Egyptian artifact on display at the Royal Ontario Museum, because the piece in question was on loan from the British Museum, which does not allow sketching. The rogue sketcher helpfully pointed out that the ROM is not, technically, in Great Britain, and therefore allowed to make its own rules, but to no avail.
