The City of London is shown in ruins after prolonged Nazi bombardment. In response to the bombing, the National Fire Service had established emergency water supply tanks across the city. As one writer remembered, ‘the sun sparkling on the surface often lent a new charm to the drab urban scene’. This tank was situated on Upper Thames Street, and the dome of St Pauls Cathedral can be seen in the background. Ginner was an admirer of the Italian artist Canaletto, whose paintings of Venice may have influenced this work.
