Sal and Mary write home to their friends in Akron, Ohio: "We have been running around like gypsies and are enjoying it — as soon as Jackie gets here we are leaving for Beirut and Athens" — a breezy mid-century travelogue penned on the back of this vivid chrome view of Tehran's 24th Isfahan Circle, where red double-decker buses and vintage automobiles orbit a lush roundabout monument while the Alborz Mountains loom snow-capped in the distance. The Iranian 10-rial stamp bears the portrait of Shah Mohammad Reza Pahlavi, giving this used card its philatelic anchor. The scene — energetic, cosmopolitan, carefree — belongs to the era before anyone imagined the world these travelers knew was about to end.
