10" dubplate sleeves from the original dubmaster himself King Tubby! Judging by the design and the printing I would guess they date back to the 80's so I'm assuming they would have housed some of Tubby's digital output from that era. Fascinating both as cultural artefacts and lovely examples of classic 80's graphic design.
Please note that although the sleeves are unused they do show some signs of their age and have slight storage wear (which I quite like as it makes each one unique). By Discogs standards they probably lie somewhere between an NM and a VG+. Also, just to be clear, they do not contain any vinyl - this is just the sleeve.
