An imperious Metropolitan Police constable thrusts his white-gloved hand toward the viewer — point duty at its most commanding — in this vivid hand-tinted novelty postcard that conceals a charming accordion fold-out of London landmarks tucked beneath the officer's feet. Published by Valentine & Sons, Ltd. of Dundee and London, the card is a "Printed Paper Mailing Novelty" stamped as approved by the G.P.O. for Printed Paper Postage Rate, a clever economy measure that let senders mail the fold-out without paying letter postage. When the flap is raised, a strip of miniature black-and-white views cascades out: Westminster Abbey, the Bank and Royal Exchange, Buckingham Palace, a bridge on the Thames, Marble Arch, and Regent Street — a pocket tour of imperial London for whoever received it, perhaps a friend of a traveller named Mabel or George doing the sights. The constable wears the distinctive domed custodian helmet and sergeant's chevrons, with badge number visible; behind him, a period motor bus and Edwardian shopfront complete the scene. The reverse is unused, numbered No. 397 in pencil.
