Lord John was a British men's fashion retailer, which opened its first store at 43 Carnaby Street, London, at the corner with Ganton Street, in 1963. The first Lord John boutique was opened by the brothers Warren, Harold and David Gold in Carnaby Street in 1963, and the choice of name led to litigation from John Stephen who already owned several fashion shops in the street. In 1967, the store had a three-storey high giant psychedelic mural on the outside of the building, painted by the then largely unknown pop-art collective Doug Binder, Dudley Edwards and David Vaughan (BEV).
