I claim the ornamental design for a paver, as shown and described.
FIG. 1 is a perspective view of a paver showing my new design;
FIG. 2 is a top view of the paver of FIG. 1;
FIG. 3 is a front view of the paver of FIG. 1;
FIG. 4 is a right side view of the paver of FIG. 1;
FIG. 5 is a rear view of the paver of FIG. 1;
FIG. 6 is a left side view of the paver of FIG. 1; and,
FIG. 7 is a top view of the paver of FIG. 1 with its environment shown in broken lines.
The broken lines in all drawing views are included for the purpose of illustrating portions of the paver tha form no part of the claimed design. The broken line showing of the like pavers in FIG. 7 view represents environmental subject matter. None of the broken lines form a part of the claimed design.
