Actually, if a person has the means to pay for 
every cel of a particular character and has the 
tremendous luck of getting every cel of that 
character, then that's their perogative.  

In terms of your friend's situation, there was 
absolutely no reason for the person to contact 
your friend and tell them not to bid on an 
auction.  They have no right to do that.  Nor do 
they have the right to tell your friend how 
aweful it was that your friend won.

In my situation, I've never told anyone not to 
bid on an auction.  At the height of our LU 
bidding frenzy I know I could COUNT on being bid 
against by Lady Zatara and another girl (sorry I 
forget her name).  You pretty much could 
guarantee that one of us would be the winner of 
an auction.  And in all that time I never 
received any derogatory emails (nor sent any) to 
them.  In fact, I remember one email from Lady Z 
congratulating me on a good bidding war for an 
auction!

I'm talking about getting an email from a perfect 
stranger who INSISTED that I should NOT bid on 
the same auction as she was because I had TOO 
MANY Last Unicorn cels (as if there was such a 
thing!).  Even after I told her that I only bid 
on auctions if I don't have a cel from that 
scene/sequence I was email flamed.  I'm not so 
sure that there is 'another side' to this 
particular situation beyond the fact that she 
wanted something she probably couldn't afford to 
have.  You have to admit when your max bid is 
something around $100 on a book Last Unicorn cel 
(one where there was a foreground and 
background), the odds of her winning were slim!
