The 6-cent Cherokee Strip commemorative stamp was first placed on sale at Ponca City, Oklahoma, on October 15, 1968.
This stamp marked the 75th anniversary of the dramatic land rush into the northern part of the state, where 40,000 homesteads of 160 acres awaited successful claimants. More than 100,000 prospective homesteaders were on the Kansas border awaiting the signal that began the run on September 16, 1893.
The stamp was designed by Norman Todhunter and was issued in panes of fifty, with an initial printing of 120 million.
