Abstract
Abstract A photographic display apparatus which comprises a substrate, as for example, a glass sheet having a mirrored surface thereon. An orthochromatic, high contrast, graphic arts copy film, or so-called "ortho film," having a positive visual image is disposed on the substrate and is covered by a transparent sheet. These three components may then be secured together by conventional means. The image on the ortho film is viewed through the transparent sheet against the mirrored surface of the substrate and which presents a unique visual appearance, similar to that of an image etched onto glass. The ortho film may be made by using a positive print of the desired image and generating a negative film therefrom through conventional photographic techniques. This negative film may be printed and enlarged if desired during the printing process in order to produce a positive ortho film sheet which is used in the above photographic display apparatus.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
118 words
A photographic display apparatus presenting an effect similar to etched glass, said display apparatus comprising: (a) a substrate having a mirrored surface thereon, (b) an orthochromatic high contrast graphic arts copy film sheet of the type used in making line reproductions in lithographic processes, said film sheet having a visual image thereon incidental to a surface of said substrate, (c) a transparent sheet incidental to said ortho film sheet such that the film sheet is disposed between said substrate and transparent sheet so that one may view the image on said film sheet through said transparent sheet against said mirrored surface, and (d) means to hold said substrate and transparent sheet in incidental relationship to said film sheet.
Claim 2
Dependent Claim
118 words
A photographic display apparatus presenting an effect similar to etched glass, said display apparatus comprising: (a) a substrate having a mirrored surface thereon, (b) an orthochromatic high contrast graphic arts copy film sheet of the type used in making line reproductions in lithographic processes, said film sheet having a visual image thereon incidental to a surface of said substrate, (c) a transparent sheet incidental to said ortho film sheet such that the film sheet is disposed between said substrate and transparent sheet so that one may view the image on said film sheet through said transparent sheet against said mirrored surface, and (d) means to hold said substrate and transparent sheet in incidental relationship to said film sheet.
Claim 3
Dependent Claim
21 words
The photographic display apparatus of claim 1 further characterized in that said image on said film sheet is a positive image,
Claim 4
Dependent Claim
29 words
The photographic display apparatus of claim 2 further characterized in that said substrate and transparent sheet are held in facewise contact with opposite flat surfaces of said film sheet.
Claim 5
Dependent Claim
20 words
The photographic display apparatus of claim 3 further characterized in that said substrate and transparent sheet are relatively rigid members.
Claim 6
Dependent Claim
36 words
The photographic display apparatus of claim 3 further characterized in that said substrate and transparent sheet are relatively rigid members, and said transparent sheet is glass and said substrate is glass with a mirror surface thereon.
Claim 7
Dependent Claim
22 words
The photographic display apparatus of claim 2 further characterized in that a portion of said film sheet is at least somewhat transparent.
Claim 8
Independent Claim
102 words
A method of making a photographic display apparatus presenting an effect similar to etched glass, said method comprising: (a) generating a film containing a desired image to be displayed, (b) generating a print of said image on an orthochromatic high contrast graphic arts copy film and where a portion of said film is at least somewhat transparent, said film being of the type used in making line reproductions in lithographic processes, and (c) enclosing said film between a transparent sheet and a mirrored substrate so that one may view the image on the film through the transparent sheet against the mirrored substrate.
Claim 9
Independent Claim
102 words
A method of making a photographic display apparatus presenting an effect similar to etched glass, said method comprising: (a) generating a film containing a desired image to be displayed, (b) generating a print of said image on an orthochromatic high contrast graphic arts copy film and where a portion of said film is at least somewhat transparent, said film being of the type used in making line reproductions in lithographic processes, and (c) enclosing said film between a transparent sheet and a mirrored substrate so that one may view the image on the film through the transparent sheet against the mirrored substrate.
Claim 10
Dependent Claim
28 words
The method of claim 7 further characterized in that the film containing the image to be displayed is a negative film and the print is a positive print.
Claim 11
Dependent Claim
41 words
The method of claim 8 further characterized in that the step of generating a film containing a desired image comprises exposing a negative to a positive print of the image to be displayed and processing said negative to generate said film.
Claim 12
Dependent Claim
31 words
The method of claim 8 further characterized in that said method comprises selecting a film for generation of the positive print thereon with film characteristics to produce a desired aesthetic appearance.
Claim 13
Dependent Claim
40 words
The method of claim 8 further characterized in that said method comprises placing said substrate and transparent sheet in facewise contact with opposite flat surfaces of said film and securing said substrate and transparent sheet with respect to said film.
Claim 14
Dependent Claim
18 words
The method of claim 11 further characterized in that said substrate and transparent sheet are relatively rigid members.
Claim 15
Dependent Claim
34 words
The method of claim 11 further characterized in that said substrate and transparent sheet are relatively rigid members and said transparent sheet is glass and said substrate is glass with a mirror surface thereon.
