Even without the signature the LP is worth £25 or more, I couldn’t believe it when I opened it, the signature for Andrew Lloyd Webber checks out with other examples on E Bay etc, it’s on a sticker which looks like it’s been torn from a set so I guess he signed several stickers which were added to LP’s as a promo or for sale in the theatre? Lovely company copy, see grades above, the booklet is about EX too, good luck
