This engraving in London, on Waterloo Place not far from Trafalgar Square, is part of a memorial to Sir John Franklin, leader of an ill-fated 1840s expedition in search of the Northwest Passage through Arctic Canadian waters.

I snapped this image in September 2016, just days after it was reported the wreck a second ship from his small fleet, HMS Terror, appears to have been found intact and in perfect condition at the bottom of the appropriately named Terror Bay, Nunavut.
