I'm helping out my father in law by selling off a few of his old LPs and stumbled across this.
I'm thinking this site might be the best place to sell it as it's a fairly unusual item with a very unusual back story.
This LP was stolen from the Decca factory in London
(in the 60's i think) and has 'DEMONSTRATION SAMPLE NOT FOR SALE' printed on it
If anyone is interested let me know and i can take a pic.... for all i know it's not as rare as i thought as there's no info on the net that i can find but if anyone has an interest in it let me know
