The panoramic image of downtown Saigon above was made in November 1972, the one below in April 2000. The biggest change: Tall buildings sprout from the horizon where before only spires of the Saigon Cathedral rose. Atop the venerable Eden Building, center, a portrait of Ho Chi Minh has replaced a billboard for Pan Am (the Sanyo sign was removed but the outline remains). The City Opera, right, showed its age in 1972. Now it is restored. Both images were made from atop the old wing of the Caravelle Hotel.
