The U.S. Postal service will release a commemorative cachet envelope collector series with double cancellations to commemorate the October 16, 2011 dedication of the Martin Luther King, Jr. National Memorial and the 16th anniversary of the Million Man March which was held on October 16, 1995.

The cachet envelope for the double cancellation features a picture of the Martin Luther King memorial, complemented with the Barbara Jordan stamp. Jordan is the 34th honoree in the Black Heritage Stamp series. In addition, the cachet envelope will bear two stamps from the "To Form a More Perfect Union" issue, depicting significant events in the African American journey toward equal rights.

The two postmarks honor different dates. One cancellation bears an October 16, 2011 date, the date of the dedication of the MLK memorial. The second cancellation bears an August 28, 2011 date, which was the 48th anniversary of King's "I Have a Dream" speech.

The cachets, priced at $7, will be available at these locations in Washington, D.C. on Sunday, October 16:
