A river of dark-suited humanity surges through the financial canyon of Broad Street in this dramatic white-border-era postcard capturing the legendary "Curb Brokers" — the open-air, unruly forerunner of the American Stock Exchange — with brokers and clerks crowding the street beneath the soaring tower of what appears to be the Bankers Trust Building on Wall Street, American flags snapping in the distance above the columned facades of lower Manhattan's money temples. The descriptive text on the reverse makes the scene vivid: "a unique open-air market for the sale of stocks, which are not listed on the Exchange… a scene of great animation daily from 10 a.m. to 3 p.m." — the Curb Market formally moved indoors to become the New York Curb Exchange in 1921, making this image a rare document of a genuinely vanished institution, beloved by financial history and Americana collectors alike. Unused, clean, and bright, this card is a crisp primary-source artifact of early 20th-century capitalist pageantry.
