On the back of the card it reads:: Robert Eagle's Heart Prairie Chief in typical Cheyenne attire living in Western Oklahoma in Clinton. The majority of the Oklahoma Cheyennes are still found in this area today. This card comes from a librarian in Tulsa. She found this card at a flea market. She mentions the Trail of Tears. The Trail of Tears was a forced displacement and ethnic cleansing of about 60 000 peoples of the "Five Civilized Tribes" and their black slaves between 1830 and 1950 by the United States Government.  Cherokee ( Aniyvwiya) , Muscogee ( Mvskoke) , Seminole, Chicksaw ( Chikashsha),  and Choctaw ( Chahta)  nations were forcibly moved to the new designated Indian Territory west of the Mississippi River as a result of the Indian Removal Act in 1830. The relocated people suffered from exposure, disease, and starvation while en route to their destinations or shortly thereafter. 

Dubuque is a city of 60 000 people located along the Mississippi River; at the junction where Iowa, Illinois, and Wisconsin meet. Because of this the area is known as the Tri-State Area.  This card comes from the Dubuque Arboretum and Botanical Garden established in 1980. The grounds are  230,000 m 2 .   It is staff entirely by volunteers - about 300 in total
