An atmospheric wash study, from the Observatory, showing the heavily industrialized river to the west of the Isle of Dogs. The Queen's House and Royal Naval College are on the right and in the left lower corner is the tower of St Mary's Church (by George Basevi, 1829), demolished in 1936, where the King William IV statue now stands. It may be one of the early studies done for the large oil painting Wyllie exhibited at the Royal Academy in 1924 of which PAF0715 is practically an identical etched replica (though not from it) and PAF2095 a study for the viewpoint those take.
