On September 25, 1993, the Postal Service issued 4 stamps that featured the pioneers of country and western music.  The four were Hank Williams, Patsy Cline, Bob Wills, and the Carter Family. All made indelible contributions to the creation of American popular music. Also, on June 9 of that year, the USPS released the Hank Williams stamp separately, testifying to Williams' preeminence in the country music world.

These 5 unaddressed covers, all with the First Day of Issue cancellation from Nashville, TN on June 9, 1993 for the separate Williams stamp and September 25, 1993 for the other four, are handsomely cacheted by Mystic. Each cover has biographical info on the back too. These covers would make a great gift for the FDC collector.
