Help With This Address And Post Mark "Rose Cheerikee Nation"?

Not sure what town and in what state this is. What is the script to the left of Nation?

There is a Rose Oklahoma listed as being in Mayes County, Oklahoma. PO opened in 1891 as part of the the Indian Territory which became the state of Oklahoma in 1907. I do not have access to other information right now, but I would assume that Rose was located in the Cherokee tribe area hence Cherokee Nation.

After "Nation" I read "I. T." (Indian Territory)

Rose Oklahoma is in the territory that the Cherokee Nation was forced to move into. From Wikipedia

"Rose is a small unincorporated rural community and census-designated place in southeastern Mayes County, Oklahoma, United States, on Scenic U.S. Highway 412. The community was said to have been named for Rowe's Prairie, which is nearby. The post office was established March 13, 1891, with David Ragsdale as the postmaster. The ZIP Code is 74364."

Fantastic! Thanks both of you! I couldn't decipher the last initials.

The address makes more sense with different line breaks:
Rose
Cherokee Nation
I.T.

Here is a broad overview map from 1899 showing the division between Indian Territory and Oklahoma Territory (Frye's Advanced Geography):


And a 1900 map (Cram's Unrivaled Family Atlas of the World) showing the Cherokee Nation area of Indian Territory at the far NE corner of the current state. Rose is just above the large "E" of TER.
