Gleaming under a summer sky with three flags snapping in the breeze, the grand Copley Plaza Hotel anchors Boston's Copley Square in this vibrant linen-era postcard mailed on September 11, 1940 — just as Europe was plunging deeper into war, two friends named Peggy and Louis were having "a grand and glorious time" in Boston, raving about a "delightful boat trip up" and declaring "the beans are grand." The Copley Plaza, opened in 1912 and designed by Henry Janeway Hardenbergh (architect of the Plaza Hotel in New York), was already one of America's most storied grand hotels, and this colorful linen card published by United Art Co. of Boston captures the handsome Beaux-Arts facade with a row of period automobiles from the late 1930s parked along the square. The card was addressed to Mr. and Mrs. S.J. at the O'Henry Hotel in Greensboro, North Carolina — a nice secondary provenance linking two iconic American hotels of the era.
