Covers containing the 5 cent and 10 cent US adhesives from 1847 are all prized by collectors, and those from post offices in the Indian Nations are especially valued. Most of these covers originated from a correspondence between Lt. Clinton Lear and his wife. According to Vince King, a Texas postal history collector with whom I have corresponded;
"Military records show Clinton Lear was at Fort
Towson in June and July 1850 before heading south to Corpus Christi Texas via
San Antonio. Doaksville, near the Fort received shipments of 10c 1847
stamps and Lear apparently procured some.
I do have several covers from
the Lear correspondence (we Texans call them “Lear covers”). The one I
have was the cover he posted on his trip from Indian Territory to Corpus
Christi as he traveled south. It probably was posted on the same trip as
the one you attached…i.e. his next letter to his wife. It was posted from
Chambers Creek (TX) which is about half way between current day Dallas and
Waco. He carried the stamps (US#2) with him out of Doaksville as there is
a Doaksville #2 cover extant which was mailed at (before) the “start of his
trip”.
Most of the covers come from Doaksville. A trading post was established during the early 1820s by Josiah Doak.
With the signing of the treaties Dancing Rabbit Creek and Doak’s Stand,
Doaksville became a major destination in what later became known as
Indian Territory. With the military post nearby at Fort Towson for
protection, Doaksville became the largest town in IT in 1850 and the
commercial center of the Choctaw Nation. Read more about Doaksville on the web here.
