I've fallen in love with a bag. Although that's not uncommon, I cannot for the life of me find it anywhere.
Here are two links of Kristen Bell (star of UPN's Veronica Mars) holding said bag at the Lucky/Cargo Club event on 5/18/2005, from Something-happens.com
The first thing that comes to mind is the Paddington Saddle...but it doesnt have the chains and that bag is missing the 5-Pound lock. It could be Givenchy since McDonald likes that length and the chains...
