Hello katie,
Just wanted to tell you the cel is wonderful, it 
is not just a serenity cel it is a winged 
serenity cel from episode 200, those cel's are 
very rare and worth more then 200, figured I 
would let you know my view as I have a winged 
serenity and I know your is worth more then 200 
dollars for it. I included my web site with my 
winged serenity. If you can put it up for 
auction. I think it is a special cel. Well Good 
luck with what ever you deciede to do  with it.
