This block of four vintage United States airmail stamps, each with a denomination of 10 cents, arranged in a connected square. The stamps share a monochromatic purple design that gives them a classic, archival appearance. At the center of each stamp is an illustration of a grand building, likely representing an international institution, with sweeping architectural lines that convey importance and scale.
