How would I go about finding out the authenticity of a Fendi handbag?

I found this cute little Fendi clutch hidden away a second hand store years ago. I am looking to sell it but I was wondering how I can find out any information about this clutch. Any good info on how I can go about finding out if this clutch is authentic?|||You need to go the Purse Forums (http://forum.purseblog.com/) and have the Fendi experts look at photos of your bag to determine authenticity. If you live near a Fendi store, of course, they can tell you.
