The Chess International Blues Series is a Dutch series of 24 LP's all from the Chicago Chess label. It ran from late 1964 to 1968. The series was compiled by Muddy Waters - Electric Mud in 1968.
The first 15 volumes came with a special on 3 sides open foldout art sleeve in a special hard plastic sleeve. These where used by Artone / Funckler and CBS Holland from 1962 till early 1966. Something to do with avoiding copyrights on regular flip back sleeves. Another identifier is that the Chess International Blues Series banner on the back is blue. Most of this series was re released with regular sleeves in 1966-67. Here the banner is mostly grey. Volume 16 to 24 where released in Stereo and keep more in line with the Chess USA release timing like the series "The Real Folk Blues" and "More Real Folk Blues" . On the back there are no liner notes anymore but promo pictures from the series. Here the Chess International Blues Series banner is grey from 16 to 21 with the exception of 18 which is blue again. The last 3 volumes from 1968 have the blue banner.
