Set into the garden wall of Marlborough House at the junction to The Mall is a shallow relief bust of Queen Mary, who lived in Marlborough House.   It was done by Sir William Reid Dick, one of those forgotten RAs of the mid-century, reponsible for innumerable war memorials, President of the Royal Society of British Sculptors, a Trustee of the Tate, and the Queen’s Sculptor, responsible for a bronze bust of her now in the NPG and this rather successful plaque with its slate lettering which was only unveiled in 1967, on the centenary of her birth and after Reid Dick’s death:-
