A composite including a polymeric film having a first generally planar major surface and an opposite second major surface defined by a multiplicity of elongate parallel contiguous ridge portions. The ridge portions each have a generally triangular cross section and elongate obscured and transmitting second major surface portions intersecting at the apex of the ridge with the obscured second major surface portion being on the side of the ridge generally facing a first end of the sheet and the transmitting second major surface portions being on the side of the ridge portions adjacent a second end of the sheet. The film can provide visual transmission between its first major surface and the transmitting second major surface portions while coatings along the obscured second major surface portions prevent viewing of visual images through the film; whereas the composite can also provide light transmission between the first major surface and the transmitting second major surface portions, while the coatings along the obscured second major surface portions restrict light transmission.

A notice assembly comprising a support portion including a base part adapted to be supported on a horizontal surface, a vertical wall part having a lower edge attached to the base part and a hollow tubular part fixed along an upper edge of the wall part with an axially extending through opening in the tubular part facing the same direction as the front surface of the wall part. A display member has a portion rotatably mounted in the tubular part. That portion of the display member has a peripheral surface bearing a plurality of set of graphic symbols providing information about the location of the person (e.g., AT LUNCH, OUT OF OFFICE, RETURN SOON, IN MEETING). By manual rotation of the display member, any of the sets of graphic symbols can be positioned in the opening of the tubular part where they will be observed by a person looking at the notice assembly. Graphic symbols are provided on the front surface of the wall part that provide incomplete information about one or more of a) the location of the person, b) the time of return for the person, c) the normal work hours for the person, and c) an alternate person to contact when the person is absent; together with ink receptive means that afford application of indicia with quick drying ink from a quick drying ink applying implement or pen to complete the information, and afford subsequent removal of the ink.
