To authenticate this bag, we need clear, readable photos of both sides of the white authenticity tag (sewn inside the zip pocket). In addition, a photo of the stamped back side of the zipper pull helps us.
1. It's a large, never-used Veneta, with the mirror, so IMO the price is fair. I would also ask about any odors.
2. Without the code from the tag I can't be sure, but the color looks like Quarzo from Spring-Summer 2007.
3. It's the large size Veneta, but usually the measurements are of the body of the bag, not including the strap. So the measurements are actually about 19" wide and about 13" high. These bags slouch, especially with use, so the dimensions are approximate.
