Unfortunately the blue blob on the front cover is not part of the design! This is a very rare record label and I suspect some releases may have been of the "99 copies only variety"?
While tidying up I have found 2 copies of this, earlier copy dated JU.54/1 the sleeve is not laminated, straight cut flaps, brown paper inner which may be home made.
The 2nd copy fully laminated curve flip backs with a plastic inner sleeve,JU.56/5.
