The ornamental design for an internaltongue of a marking tag, as shown and described.
FIG. 1 is a perspective view of our internal tongue of a marking tag
showing the cut of the tongue and the two holes of the tongue base in full
lines and showing broken lines for environmental structure (i.e., a
marking tag) forming no part of the design to be patented; and,
FIG. 2 is a perspective view of the design in FIG. 1, with the tongue
displaced from the plane of the tag.
The rear of the tongue duplicates the front. All side edges are
unornamented and of uniform thickness. The tongue is internal in the sense
that no part of it connects to the periphery of the marking tag.
