Known reproduction has blurry photos on front; check the second photo from the left at the bottom on the front cover; the words "Theatre Royal" should be visible on originals above Jonh's head.

You should also check out for the following: disk label on the reproduction incorporates new print on a slightly blurred reproduction of the Apple label, which is particularly blurred on the perimeter print "MANUFACTURED BY APPLE...".
