Comment by PhilMH:
Discogs has a UK entry where the disc is made in England, so I suspect that this Netherlands pressing wasn't made for the UK; the "Imported From Europe" sticker on the cover makes me think that this was intended for the USA (and Canada?), as the PolyGram companies there typically imported European pressings for North American release, and trumpeted that fact in their ads in the Schwann catalog, this one being listed in Philips/Phonogram's ad in Schwann's September 1976 issue.
