Mailed from New York's Grand Central Station on January 3, 1917, this luminous Phostint photochrome card captures the soaring choir stalls of the Cathedral of St. John the Divine — the world's largest Gothic cathedral, then still under active construction — in a golden wash of amber woodwork and marble arches receding toward a radiant apse. The writer, mailing to "Miss M.L. Barry" in Philadelphia, mentions being at "Grand P.M. at Grand Central's side" and references Long Island and a friend named "Belle," painting a vivid picture of wartime-era New York social life just as America stood on the brink of entering World War I. Detroit Publishing Company's proprietary "Phostint" process — a Swiss-derived photochrome technique — gives this card its characteristic rich depth of color, far superior to contemporary halftone prints. The card carries no stamp, as the prepaid "Phostint" cards required a separately purchased 1¢ stamp for mailing, which appears to have been removed or was never applied — yet the Grand Central postmark confirms it passed through the mail.
