The first four discs are identical to Eight Classic Albums on the parent label. Neither release indicates stereo/mono (but the "stereo" concept is a forced one anyway as they would have been highly unlikely to be recorded in true stereo in this period).
Packaging is a carboard box with carboard sleeves holding the disk. No booklet of any kind. Each carboard sleeve has a picture with no relation to the albums on the CD. Each sleeve lists the albums and tracks on the media.
The TOC on each disk identifies the album name as '6Cd'.
