I'll go out on a limb here (dear lord, shoot me now).
I own an authentic Parchemin Clemence bag with palladium hardware from Hermès. I purchased it from my long-time sales associate at Hermès. It is undeniably authentic. The photos you supplied on your eBay listing, and in the supplemental photos you emailed to purseinsanity, do not have enough high-resolution clarity for me to compare the bag in question to my own authentic bag. So, I would hesitate to encourage purseinsanity to purchase your bag without further very close-up images of the kind discussed in post number one of this authentication thread.
