If seeing all this great art on the streets has got you inspired, this is your chance to join in. We've set up a Grand Tour™  Flickr group that we'll be selecting images from to appear on the site, so dust off your camera (or mobile phone) and upload your pics. From policemen admiring a Constable, to divas discussing da Vinci, show us how the Old Masters fit into your London.
