Signed record sleeve...Early years

[Jim.]

Hi, new to the forum and just after a bit of advice really. first post so hello all.
Bit of background... My late father was a DJ and compare back in the day and went all over the place rubbing shoulders with many groups.
I have his record collection and amongst it all sorts of memorabilia.

I came across this white 7in sleeve signed by

Peter Green
mick Fleetwood
John McVie
Danny Kirwan
Jeremy Spencer

I'm just intrigued by it really so thought I'd post in here. Although I'm a fan and went
to see the band a couple of years ago I know nothing about autographs.
Is this sort after, rare or have any value? (other than sentimental to me)



Thanks in advance,
Jim
