The ornamental design for a necktie with a pocket, as shown and described.
FIG. 1 is a front perspective view of the necktie with a pocket according to my new design.
FIG. 2 is a front perspective view of the necktie with a pocket in use; and,
FIG. 3 is a side perspective view of the necktie with a pocket.
The fine dotted lines along the surface of the necktie with a pocket illustrated in FIGS. 1-3 depict claimed stitching. The tied knot outlined by broken lines that is adjacent to the necktie with a pocket in the view of FIG. 2 depicts environmental structure that forms no part of the claimed design. The partial human figure outlined by broken lines in the view of FIG. 2 assists to illustrate how the necktie with a pocket may appear when in use and forms no part of the claimed design.
The surfaces of the necktie with a pocket that are not made visible beyond the perimeter structural edge lines of the necktie with a pocket in the drawing disclosure form no part of the claimed design.
