I don't collect items from my fandoms, usually. Maybe a T-shirt or button, a piece of related jewelry, or a stuffed animal (I have a wolf and panther Beanie Babies). Part of this is just my nature; I'm not a collector, except of stories. Part of it is lack of funds.
I can't even afford to think about the fact that the miniature version of Grissom's office used on CSI last season is up for charity auction.
If you are rich, and want to support the deserving and well-chosen (for a prop from this particular arc) charity, go here to view the auction data and to pre-qualify.
The charity is The National Court Appointed Special Advocate (CASA) Association, which supports the work of over 900 local CASA program offices across the country to provide much-needed advocacy to children who are victims of abuse and neglect.
