Another tantalising thing about Parlophone was that, like the other EMI labels Columbia and HMV, Parlophone's label changed in 1962 - just after The Beatles released their first LP and single. A few copies were issued on the old label. Consequently, if you have a stereo copy of Please Please Me on the old black/gold label (see picture) you are looking at over £1000 worth of memorabilia.
The fact that The Beatles recorded for Parlophone has made the collecting scene for their discs very buoyant, with an almost rabid attention to detail regarding any change Parlophone may have made to label design, even going so far as to distinguish between upper and lower case letters printed around the rim of the label on Beatle singles! Clearly there isn't the room here to go into that much detail, but one change EMI made to all their labels in 1964 was to include the words "sold in the UK subject to retail price conditions. See price lists". The change can be seen between pictures two and three. The wording appears under the yellow Parlophone name, and is a good general way of assessing whether that copy of one of The Beatles' frst two albums is an original pressing.
Again like other EMI labels, the wording was removed in 1969 and the album label became black and silver (bottom picture).
At this time Parlophone lost some of it's acts to the newly created Harvest label.
