Rising above the colonial heart of Mexico City, this early-1900s color-lithograph postcard captures the Metropolitan Cathedral in warm ochres and dusty blues — its twin Baroque towers and gilded dome dominating the skyline above a screen of tropical trees. Card No. 63 in a numbered series, the reverse carries a thorough publisher's description noting the cornerstone was laid in 1573, that the great bell alone cost $10,000, and that the cathedral's altar was once called the richest in the world before repeated plundering — a tantalizing historical footnote pressed into this small rectangle of cardstock. The card was never mailed; the stamp area specifies "Domestic One Cent / Foreign Two Cents," dating it firmly to the undivided-back era before 1907. Creasing is visible at corners and a horizontal fold crosses the upper card, consistent with age; color remains vivid.
