My latest purchase to complete my 'classic Yes era' vinyl collection - Relayer signed by Roger Dean (the album cover artist).
It was expensive, and I'm kind of taking it on trust that the sig is genuine - based on the seller's profile, I have good reason to believe that it is real; it is, however, also a bit of a lesson - don't buy stuff in the middle of the night without properly scrutinising the photos; the seller in this case didn't explicitly point out a fairly major flaw, even though it is clearly visible in the photos they uploaded - I just didn't bother to look at them closely enough; I was perhaps a bit hasty because of the pretty rare nature of the item, and that it would likely be snapped up quickly. The cover is slightly damaged, but it also has some writing in biro above the logo which is quite annoying, but I'm hoping that I can get that fixed a bit, but otherwise I'm pretty happy with it.
I also have 'Fragile' and 'Going For The One' on vinyl, the former being one of Roger Dean's most iconic and classic album covers - it's not on the shelf because I don't have room, but it is there. GFTO is not a Dean cover but has Dean's classic Yes logo - it was designed by Hipgnosis, who also did 'Dark Side Of The Moon' among many other classic rock album covers, but GFTO was, alas, not their finest hour - great if you like naked men's butts, but not my cup of tea. Their next album, Tormato, was also Hipgnosis and was arguably one of their worst album covers, so they brought back Roger Dean soon after that.
