This is a gently used 6-disc cd box set by FLEETWOOD MAC titled THE COMPLETE BLUE HORIZON SESSIONS 1967-1969. It's a 1999 Sire Records release, #73003-2. All 6 cd's are in very good, clean condition.
An ultimate must have for the music and the book and the box. I lost mine ten years ago in a flood so to find this one, in mint, well, somehow I feel better. You will too when you give it a listen!
