In May 1998 Alexander introduced his "Delta Series", of paintings during his annual "Arkansas Schools Tour". The tour was made bigger that year to include stops in Greenville, Mississippi and Memphis, Tennessee. The "Delta series" included paintings of scenes in the Mississippi Delta region of the United States from Monroe, Louisiana to Memphis, Tennessee. It includes a painting of Graceland, Elvis Presley's former home, the "Greenville Courthouse" in Greenville, Mississippi, a painting of the famous "Beale Street" in Memphis, and his painting of a "Cotton Farm" among others. Alexander's most popular series of drawings, "The Sixties Series" has been shown in schools, libraries, and art galleries in several cities since it was completed in 1993. It is made up of drawings of well known people and events of the 1960s, such as the "Selma to Montgomery marches" of 1965, and drawings of Martin Luther King Jr., Lyndon Johnson, Malcolm X, Medgar Evers and Rosa Parks. This series also has drawings about the Vietnam War.
