   DETAILED DESCRIPTION OF THE INVENTION 
   Referring now to the drawing, mounting template  16  is mounted on drywall  10  via nails  14  which are inserted into clips  12  placed in selected apertures  11  in drywall  10 . The shaft  14 ′ of flat heads of nail  14  key into aperture  22  and seat in narrow portion  22 ′ of mounting template  16  ( FIG. 1   b ). Double-sided mounting tape  18  is adhered to mounting template  16  and artwork or sign  20 . 
   Typically, steel forms mounting template  16  and can have a thickness of from a 32nd of an inch to an eighth of an inch with keyholes cut into it such that the shaft  14 ′ of nail  14  can seat itself in so that any assembled part can hang on the drywall surface. Mounting template  16  can be cut from any sheet material that can be cut to an exact shape using any known of plotting machine such as, for example, laser, waterjet, plasma and like plotters. 
   Tape  18  can be any known double sided adhesive tape, or gel-to-solid adhesive material, that will allow enough space between mounting template  16  and artwork  20  so as to accommodate the head  14 ′ of nail  14  via a relief aperture  17 . 
   Artwork or sign  20  can be any properly shaped sheet cut material that would be from the outermost finish of a given image. This material can also be cut to shape from any sort of sheet material ranging in thickness from forty thousandths of an inch and upwards. Artwork  20  can be cut from any sheet material that can be cut to an exact shape using any known plotting machine such as, for example, laser, waterjet, plasma, and like plotters. 
   Clip  12  can be any suitable Molly-type drywall insert, sized to accommodate nail  14  and hold it firmly in place. 
   The invention can use any vectored file of any drawing, artwork, logo, or symbol done in digital form which can be broken down as a collection of lines that can be positive (ie., white) on one side and negative (ie., black) on the other. Each should be closed in as objects such that they are, or can be made to be, individual pieces. The color differences describe the visual polarity that makes an image appear as it does when a sign is made on a blank wall. 
   Artwork  20  can be any drawing, logo, or symbol, as a collection of lines and parts, visually conveying a certain item, action, verbage, and/or perspective. 
   A locator template  13  for positioning clip holes can be a printed rendition of the entire image, in its actual size and dimensions. What material it&#39;s made from, or printed upon, is only limited by its compaction and storability properties, its strength, and how easy it will be to print on. Most locator templates are made from paper because they will only be used a few times. 
   If an image is only two colors, two exact colors, such as black and white, or even green and blue, it is preferably described visually in those colors in a positive/negative format. Thus one color, for example the negative, would be the background, ie, the drywall. The other color would be the image comprised for mounting template  16 , tape  18  and artwork  20 . In positive/negative format, shading (such as the color gray would be in a black and white image) is not possible. 
   Beginning with a vectored drawing of any sort of artwork, company logo, or symbol (that is completed in black and white, or positive and negative form) two renditions of the same image are made. One copy of this image is a true and exact printout of the lines making up the image using whatever size printer may be required to match the actual size of the image on paper. The general size of both images will be limited only by the size of the machines that can print, and cut them. 
   Along with the lines making up the image, this printed drawing forms the locator template which has numerous printed keyholes  22 ,  22 ′ placed in such a manner as to allow for ample area for tape  18  to have an abundant surface area to effectively hold mounting template  16  and artwork  20  together. The placement of these keyholes will be unique to every part of a given image and allow for variables in drywall frame construction to not be in the way of whatever keyhole the installer chooses to use. Keyholes  22 ,  22 ′ are laterally abundant, or even redundant, as framework studs run vertically. The keyhole arrangement on the locator template is custom engineered according to the support required for every different piece of every different image that is produced. Keyholes  22 ,  22 ′ are identical both on the paper template and in the cut sheet material mounting template  16 . 
   The invention can be used to mount cut sheet materials directly to drywall of any known dimension. In the process of mounting, an installer first places the paper locator template  13  on a wall using masking tape. Once centered, and leveled, on the wall, the installer then searches to avoid framework studs behind drywall  10  that will prevent clips  12  from spreading on the backside of the drywall. 
   Once the installer locates, on the paper locator template  13 , the appropriate number of keyholes as prescribed by the installation requirements of the given image, the installer will punch a small indentation, through the paper and into the wall in the exact location of  22 ′, the center of the uppermost aperture of the keyhole printed on the paper template. The installer uses a pointy felt tip pen to place a small, colored, mark where the indentation was made in the drywall. This will enable the installer to easily see the indentations once the paper template has been taken down. 
   Once all the required holes  1  have been marked, the installer removes the paper locator template  13  and makes holes in the drywall where every corresponding indentation has been made. The installer inserts a clip  12  in every drilled hole  11 . The wall is now ready for installation of the image. 
   Another copy of the same file is then engineered such that it can be cut from the top finish product ( artwork, etc.,  20 ) and assembled. There are three layers of material making up the pieces of any given image. The artwork  20  is the finish material, be it metal, carbon fiber, plastic, wood, etc., and can have a thickness ranging from thousandths of an inch up to ⅜ of an inch depending on its weight per square inch. The finish pieces are then attached to mounting template  16  via tape  18  which can be a double sided automotive trim tape such as made and sold by 3M Company. Mounting template  16  and artwork  20  are bonded together in such a way that all of their edges match and there is no overhang unless the design of the image calls for it. 
   While artwork  20  can be made of multiple pieces, mounting template  16  can come from the material cutter in one piece with the keyholes engineered into it. Mounting template  16  may be in more than one piece of layer without overlapping. The backside of mounting template  16  can be painted so as to prevent rusting and the front can be treated with alcohol to promote bonding with tape  18 . Artwork  20  is placed onto tape  18  leaving clearance around keyhole  22 ,  22 ′. After tape  18  has been laid onto mounting template  16  the front side of the template can be painted. A removable cover sheet on tape  18  can be left in place until one is ready to attach artwork  20 . 
   Once assembled, each part of the whole image has three layers (mounting template  16 , tape  18 , and artwork  20 ) with numerous keyholes that an installer can use any one of. To install nails  14 , the installer inserts the nail head through the larger end of the keyhole and moves it up so as to seat shaft  14 ′ in portion  22 ′ of the keyhole. All keyholes  22  are engineered with the smaller ends up and the larger ends down. 
   The installer now places a small piece of tape over the larger, bottom end  22  of the keyhole so as to keep the nail in place during object placement on the wall. Once all the nails to be used are in place, the installer holds the image piece to the wall and pushes it into the corresponding clips that have been placed into the drywall. As the nails go into the drywall, the clips spread and clamp themselves onto the nails, and the assembled piece stays attached to the wall. When all pieces have been installed into the wall, the image is complete.
