Five years later after the OP made her original request, it looks like something made by Marc Jacobs, but probably no longer available since this is so oooolllldddd. Might keep an eye out on the 'bay.
Haha, I am a Gilmore Girls addict and knew exactly what you meant when I saw the title. I also remember hearing that that is an MJ purse. I tried to find the name but didn't see anything. :/
im pretty sure that's it's MJ, but its a veeeeeeery old style. best bet is to search ebay! ive never seen that particular style on ebay, but ive seen some similar styles from the same line.
