A PBS interview with the team that won a National EMMY for what was — at the time — an untold story:  African American history in the old west.  Their 1973 documentary, “Through the Looking Glass Darkly,” had higher ratings than any of the network shows the nights it aired.  A high definition restoration of the original program was paired with this interview on the 30th anniversary.  Bob Dotson, produced, wrote and narrated.  Photojournalist Oliver Murray was also an associate producer, as was George Wesley.
