You're damn right! I feel a similar way for Andy Warhol's stuff. It's ace! But I don't have any.
Even so... It's nice to have things!
To be honest, I wouldn't have much use for Stephen Fry's tie. It would be a cool thing to have, but I wouldn't want to pay so much.
Oh Andy Warhol, a true icon! equally unaffordable...
I wouldn´t have use for his tie either (could not possibly wear it
) But I´d love to have a signed copy of "The Stars´ Tennis Balls" or - even better - "Making History" which I am reading at the moment... excellent
Of course, it is nice to have things, but hey, there is only so much space in a flat
And one will appreciate the things s/he cannot have a lot MORE (like a Jaguar XJ4 aaaaah...)
(Have you ever tried charity shops to find SF stuff at a price you can afford...)
