The white boots are the same as the early Anderson brothers and several other including Timothy Wilson "I must love you", Dave Newman "Make up your mind", Sandra Phillips "World without sunshine" wdj plus some others. Coarse vinyl, with a ridge around the middle of the label. The Anderson brothers were even sold on the GSF sleeve. They are a different batch entirely to the clever Soussan boots with PB on the run out. Very common around Nottingham once upon a time. With the exception of Tim Wilson, which was black on pale blue, everything done was black on white to keep it simple I expect. They weren't particularly numerous in the grand scheme of things.
Pete S is right, normally sold for about £8 a copy. Some friends got burnt because they believed the dealer rather than me, hey ho!
