Standing as immovable as the empire they guarded, two Household Cavalry troopers in gleaming crested helmets hold their post at the arch of Horse Guards, Whitehall — one mounted on a dark bay, one on foot with drawn sword — in this razor-sharp real-photo postcard from Valentine & Sons that captures the ceremony and pageantry of London at its most theatrically British. The sepia-toned RPPC photograph is exceptional in its detail: the cuirasses, the flowing white plumes, the leather breeches, every inch of saddlery, all rendered with the luminous precision of a true silver-gelatin real photograph pressed to postcard stock. The card was mailed from London in May (postmark partially legible: "3 [day] MAY") to Mr. & Mrs. F. Brinkman at 254 Broad Street, Sumter, South Carolina, bearing a King George VI 2d orange stamp — printed during his reign (1936–1952), placing this mailing almost certainly in the late 1940s. The sender, June, writes with the infectious excitement of a traveler smitten: "Hi! We just love England — spent 9 days in Paris, that's a wonderful place too — even if we can't speak French! How's Sumter treating you? Do write us soon. We long for mail. Love, June." The return address given is 9 Lancaster Court, op Lancaster Gate, London, W.2.
