I have this "fully" signed Rocks LP in my collection, won back in 1998 in a fan club competition. Autographs are in black permanent marker; Roger's and John's are a bit smudged, probably by Brian when he put his autograph above theirs.
I'm willing to sell it, but I haven't got a clue about the possible value. Anyone?
Also, if anyone is interested in buying, of course feel free to drop me a message.
