Just saw this auction, which takes place in the UK on 8 May.

There seems to be a suspiciously remarkable range of top quality stuff - I assume too good to be true, particularly as the certificates are not shown and the estimates for some things like signed LPs look far too low (e.g. Hendrix, Bob Marley, AC/DC, Bowie).
In particular, what do people think of these? I have more doubts about some (e.g. Marley and Hendrix) than others but all seem rather clean.
Rolling Stones

Led Zeppelin


Hendrix

Bob Marley

Bowie

AC/DC

If all the items are from a single collection I would have thought the auction house would make a big thing of this.
