Various Artists, "Blues Are Black" [VG Used]

This is a used LP. Vinyl: VGCover: VG- 197? compilation, Harlem Hitparade. Blues compilation.  Year of release is unknown but would say mid-70s or so based on the cover cardboard, etc.  Features tracks by John Lee Hooker, Memphis Slim, Brownie McGhee & Sonny Terry, Lightnin' Hopkins, and Big Bill Broonzy -- one track per artist on each side (so a total of two tracks per artist).   The LP is in VG condition with some minor surface wear, a bit of surface noise here and there, an occasional tick or pop.  Good blues compilation.  Cover has rubbing and ring wear, edges show shelf/storage wear, bottom left corner is a bit worn.
