I claim the ornamental design of the identification tag for luggage, as shown and described.
FIG. 1 is a downward frontal rightward perspective view of an identification tag for luggage according to my new design;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a left elevational view thereof, a right elevational view thereof being a mirror image of FIG. 3;
FIG. 4 is a rear elevational view thereof;
FIG. 5 is a top plan view thereof; and,
FIG. 6 is a bottom plan view thereof.
In the drawings, the circular features shown in broken lines in FIG. 4 represent portions of the identification tag for luggage which form no part of the claimed design. All other broken lines represent stitching.
