Description: The stamp features an architectural illustration of the Irish Pavilion built for the global exposition in Flushing Meadows, New York. The clean, angular lines of the two-story white structure include a centralized courtyard alongside a distinct modern stylized version of a medieval Irish round tower rising from the core. The background blends smoothly from a deep violet-purple down to a golden sunburst yellow hue behind the complex. The name of the nation, "ÉIRE," is crisply inscribed in white block lettering across the upper-left quadrant. The bottom left field carries the identifying text "IRISH PAVILION NEW YORK WORLD'S FAIR 1964-5," balanced by the large face value denomination "5P" rendered in the lower-right corner. A series of dark, wavy black lines from a machine postmark run horizontally across the face, marking its transit through the postal network.
Circa: 1964-1965
Condition: Used - Hinged
Notes:
This stamp was released as one of a two-value commemorative set to publicize Ireland’s participation in the 1964–1965 New York World's Fair, which attracted over 51 million total visitors. The striking architecture on the stamp was designed by the celebrated Irish architect Andrew Devane. The actual physical building featured an outer double wall crafted from random, large pieces of gray Lisconner stone and reddish-brown marble to give the modern building the robust texture of an ancient Irish castle.
