Blazing against a cobalt-blue twilight sky, the Catedral Metropolitana of Mexico City glows in golden floodlight in this stunning 1968 chrome-era night photograph — one of the most dramatic architectural images ever captured of the Western Hemisphere's largest and oldest cathedral. Construction spanned nearly 250 years (1573–1813), layering Gothic, Baroque, and Neoclassical styles into a single breathtaking façade. Jack sent this card to Mae on May 4, 1968, writing enthusiastically about the city's many sights, its beautiful old buildings, and a climate he described as "just like June for 12 months of the year" — a traveler's postcard-perfect endorsement. The card bears a rare Mexico 1968 Olympics airmail stamp (80¢ Aéreo), issued just months before the Games opened in October of that same year, making it a philatelic time capsule of one of Mexico's most significant cultural moments.
