FIG. 1 is a perspective view of a glittering retroreflective sheeting showing the new design. The speckling that is shown in this Figure and in FIG. 2 represents glitter that is displayed by the article when exposed to light. The terms “glitter” or “glittering” are used herein to mean a multiplicity of discrete regions of light that appear as distinct points of light, each of which may be noticed by the unaided eye of an ordinary observer when light is incident on the sheeting, but which points of light disappear or become unnoticeable to the eye of the same observer when either the angle of the incident light source to the sheeting, the angle of observation, the sheeting's orientation, or a combination thereof are changed. The term “retroreflective sheeting” means a sheeting that reflects substantial quantities of incident light—which light otherwise would be reflected elsewhere—back towards the light source.

FIG. 2 is a reduced scale top elevational view thereof.

FIG. 3 is a bottom elevational view thereof.

FIG. 4 is a front side elevational view thereof. The rear side elevational view is the same as the front side elevational view; and,

FIG. 5 is a left side elevational view thereof. The right side elevational view is the same as the left side elevational view.

In the drawings, the broken lines form no part of the claimed design and indicate that the glittering retroreflective sheeting has indeterminate length and width.

The combination of diagonal surface shading and stippling in FIGS. 1-2 represents a glittering reflective surface effect.
