I claim the ornamental design for a handbag, as shown and described.
FIG. 1 is a front view of the handbag showing the front zippered pocket in the closed position;
FIG. 2 is a rear view of the handbag showing the rear zippered pocket in the closed position;
FIG. 3 is a side elevational view of the handbag;
FIG. 4 is a side elevational view of the opposite side of the handbag;
FIG. 5 is a bottom plan view of the handbag;
FIG. 6 is a top plan view of the handbag;
FIG. 7 is a front, side and top perspective view of the handbag showing the front zippered pocket open;
FIG. 8 is a rear, side and top perspective view of the handbag showing the rear zippered pocket open having a central flap in the down position and a pen in place in the pen holder tab; and,
FIG. 9 is a rear, side and top perspective view of the handbag showing the rear zippered pocket open having a central flap in a partially up position and a pen in place in the pen holder tab.
The broken line showing of a environment in FIG. 8 and FIG. 9 is included for the purpose of illustration only and forms no part of the claimed design.
