Vintage postcard from 1971 features a vibrant color photograph of Trafalgar Square in London, highlighting the iconic fountains, Whitehall, and Big Ben in the distance. The scene captures a bustling day with classic red double-decker buses and period-appropriate crowds. This authentic piece of travel ephemera was postmarked in London on September 22, 1971, and sent via Air Mail to California. It includes a handwritten message and a 4p British postage stamp, making it a wonderful addition for collectors of British landmarks or postal history. Published by The Photographic Greeting Card Co.
