ok take the White Album or Sergeant Pepper, some prints of those are valuable, some are not.
Ok - Sergeant Pepper - three scenarios
1. say there was only
a first edition pressing made, nothing subsequently - you'd have to admit they would be more valuable than what the first edition pressing sells for now.
2. say there wasn't
even an official pressing made just a bunch of promos sent out to reps and stations - you'd have to admit that a promo pressing would be worth more than scenario 1
3 say there was no pressing, just a single
master copy of the recording session - you'd have to admit it would more valuable than both scenario 1 & 2
Therein lies your answer
(of course this is all hinged on the Beatles becoming as successful as they did had they not released Segeant Pepper at all - but that is irrelevant here as the success of the picturemate was evidently a non-event and it was still initially
highly sought after until recently)
