Lorie from USA has sent me this postcard, and I like it very much! She also told me about Memorial Day.
On the postcard you see Iron Breast, Piegan, by Edward S. Curtis. The card also has the quote of Luther Standing Bear, Lakota Sioux Chief: "The American Indian is of the soil, whether it be the region of forests, plains, or mesas. He fits into the landscape".
Thank you, Lorie!
