The broken lines shown in the drawings illustrate portions of the handbag—namely, a brand name and logo, a clasp, shoulder strap attachment rings, and rivets—that form no part of the claimed design. The shading lines shown in the drawings represent the approximate three-dimensional contour of the design and do not indicate surface decoration. In FIG. 7, the shoulder straps are omitted to show the top of the body of the handbag.
