Vivid color photographic postcard documenting the 1970 eruption of Hekla, Iceland's most active volcano. The image shows the Oldugigar crater in full eruption — glowing orange lava flows streak down the dark volcanic cone while a plume of ash and smoke billows into the blue sky; the snow-covered summit of Hekla proper is visible in the background. Caption: "HEKLA 1970." Trilingual back (Icelandic, English, German): "Varied activity in the largest Oldugigar crater. Hekla proper is snow-covered in the background. June 5th, 1970."
