The ornamental design for a visor, substantially as shown and described.
This new design is related to that in my U.S. Design patent application Ser. No. 29/292,556 entitled “Cap” that was filed on Oct. 17, 2007 and issued as U.S. Design Pat. No. 572,437 on Jul. 8, 2008.
FIG. 1 is a perspective view of a visor showing my design;
FIG. 2 is a perspective view at a different angle of the visor;
FIG. 3 is a front view of the visor; and,
FIG. 4 is a rear view of the visor.
The broken lines shown in the drawings illustrate stitching and are part of the claimed design.
