Hm, this entry appears to be something of a hodge-podge...
We have the cat# and date for the original USA mono release, but there are 16 tracks instead of 12. The cover images { 503352, 1210241 } look to be from some later reissue. The labels { 2835269, 2835270 } are from an original 1964 stereo pressing.
This LP was again brought on the market sometime in the seventies or eighties. That is when I purchased it. The reissue looks a bit like a bootleg. Above the hole, the label shows the NCB logo, for Nordisk Copyright Bureau. Nothing else points at a Scandinavian origin. The original LP was published in 1964, without the NCB logo I suppose.
