The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof. 
     DETAILED DESCRIPTION OF INVENTION 
     As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention. 
     The purpose of the present invention is to produce a writing surface that is erasable with any desired writing utensil such as a pencil and eraser, or permanent with a ball point pen. In one embodiment as shown in FIG. 3, the writing surface is sized as a small personal memo device in the form of a book. It may be sized so that it is suitable for pocket or purse or usable as an organizer accessory. 
     In another embodiment, the graphics of the present invention may replace a typical “to-do list ” or paper. Typically, if one writes “to-do” items on paper, it is necessary to rewrite un-done items to the next day&#39;s list. This re-writing is eliminated by the present invention. A person need only erase done items. Un-done items remain on the list. The present invention may also replace typical little pieces of paper that are used as “to-do” lists. 
     In one embodiment, the writing surface of the present invention is water-resistance. This makes it useful in everyday applications and also specifically useful on boats or motorcycles or the military, where regular paper is less useful. In another embodiment, the present invention may contain any graphics including art work, advertising messages, a calendar or a specified message (e.g. “to do list”) that is laminated between the two plastic layers (i.e. panels). 
     In another embodiment, as shown in FIGS. 5,  10 A and  10 B, the writing surface is adhered to the back of a camera to record various data. In further embodiments, the writing surface may be sized to work with a measuring tape to jot measurements. In yet another embodiment, the writing surface can be size to be adhered to medical instruments to jot down settings that can be changed. 
     The advantages of the present invention include: (a) it can be sized for any application (e.g. for a “Palm Pilot”); (b) it is light weight; (c) it is durable; (d) it is water-resistant; and (e) the graphic potential for art work or advertising is limitless. 
     As shown in FIGS. 1 through 3, in one embodiment, the writing surface is constructed of two laminated panels that are hinged together. In one embodiment, one side of the laminate is glossy and the other side is a writable matte. When the book is closed, the writable matte sides are hidden. In another embodiment, the two laminated pages may have three or four sides composed of writable matte. 
     As shown in FIGS. 8 and 9, in another embodiment, the writing surface is constructed of chemical matte polyester lamination material that has been burnished with an abrasive material. As shown in FIGS. 8 and 9, the burnishing serves to scratch the surface sufficiently to increase the erasing ability of the surface but, at the same time, reduce smudging of pencil lines. In yet another embodiment, as shown in FIG. 6, the lamination process involves a three ply structure including encapsulating a printed piece of paper or plastic that contains any suitable graphics such as advertisements, calenders or other information. In another embodiment, a matte is on one side and gloss is on the other side. 
     In one example of constructing the writing surface of the present invention, a 10 mil chemical matte lamination material may be employed. The gloss side may also be 10 mil and thus, the total writing surface has a 20 mil thick final laminated panel. In one embodiment, the writing surface may be constructed of a “chemical matte” and a “gloss ” from Transilwrap Company, Inc. For example, a lamination of seven parts polyester to three parts polyethylene glue may be employed to produce the matte surface. In another embodiment, the chemical matte surface, which is the writing surface after being burnished, may be laminated to any plastic substrate such as polyethylene or polypropylene. The substrate thickness may be closer for the desired rigidity. For example, a range of about 3 mil to about 20 mil may be chosen. 
     In one embodiment, as shown in FIG. 4, part of the writing surface is formed in a shape to hold a writing utensil such as a pencil or pen. For example, the writing utensil face may include a pencil. For another embodiment, FIG. 6 shows a pencil holder formed by heat forming part of panel  12  into the desired shape. In another example, FIG. 8 shows a picture of ReflectaNote used for flash units. 
     In another embodiment, the writing surface may consist of two panels bonded together to form a hinge. The methods of bonding may include tape or any other suitable method that holds the two panels together but allows for sufficient flexing to flex to 180 degrees. In one example, FIG. 2 shows a ½″ polyester tape ( 2  and  2   a ) that is applied to both sides of panels  1  and  1   a  to form a hinge. In yet another embodiment, matte lamination ( 3 ) with chemical matte surface ( 26 ) and gloss lamination ( 6 ), encapsulates paper or plastic ( 5 ) in the laminate&#39;s glue ( 4 ). 
     In another embodiment, as shown in FIG. 7, the writing surface is adhered to the back of a camera. In one example, the construction is matte lamination on one side with adhesive backing on the other. FIG. 8 shows an enlarged cross section partial view of FIG.  7 . Paper or plastic ( 28 ) has had an adhesive backing ( 30 ) with release liner ( 32 ) added before lamination. After lamination and trimming, gloss laminate  34   a  becomes waste.
