I claim the ornamental design for a label/postage stamp dispenser, as shown and described.
FIG. 1 is a perspective view of a label/postage stamp dispenser showing the design from its top left side;
FIG. 2 is another perspective view of the label/postage stamp dispenser, showing the design from its bottom right side;
FIG. 3 is a right side elevational view of the label/postage stamp dispenser, the left side elevational view being a mirror image thereof;
FIG. 4 is a top plan view of the label/postage stamp dispenser; and,
FIG. 5 is a bottom plan view of the label/postage stamp dispenser.
The broken line depiction of the seams in FIGS. 1, 2, 4, and 5, of the roller sleeve in FIGS. 2, 3, and 5, and of the roller ends in FIGS. 2 and 5 are for illustrative purposes only and form no part of the claimed design.
