front views.
back views of the card when placed in position.
Figures 4 & 8 are back views of the front card forming part of the composite
card.
The composite card consists of a front card A, a middle card B, and a back
card C.
The front card A is made as a frame or with an opening through which a person
viewing the picture can see the middle card. The back card C has a rectangular
recess on its upper edge. The picture to be shown is exposed on the middle
card B on which it may be printed, or painted direct or to which it may be attached.
In Figures 2 & 6 of the accompanying drawings the picture exposed through the
opening of the front card is shown by cross-hatching b.
The front card may be ornamented in any suitable manner, or if the nature of the
picture allows, it may form part of the view.
The back of the front card is covered with gelatine, metallic foil faced, varnished or
glazed paper or similar material of the colour which is to be reflected on the picture,
that is to say with red reflecting material if red light is to be shown, with green
inaterial if green light is to be shown, or blue material where blue light is to be shown,
and so on.
In Figure 4 which represents the back of the front card the surface of the reflecting
material is shown by horizontal hatching f. The same is the case with Figure 3,
which is a back view of the card when placed in position and which shows part
of the reflecting material on the front card through the recess in the back card C.
In the modified construction (Figures 5 to 8) it is supposed that the entire back of
the front card is covered with reflecting materials of various colours.
Figure 8 shows one colour, f, by horizontal hatching and the other colour f¹ by
vertical hatching. It is evident that more than two colours may be used.
The person desiring to look at the picture has to place the card so that the back
card is exposed to the source of light, either day-light, or artificial light.
From this source the back of the front card A receives, through the recess C¹,

page_text: light which is reflected by the reflecting material of the desired colour on to the
picture.
The light is reflected more to the upper, middle, or lower part of the picture
according to the degree of angle at which the card is placed.
As shown in Figures 1 to 4 the middle card B is connected to the other two cards
in such a manner that it always remains parallel to the front card A irrespective of
the angle at which the card is placed.
To effect this the middle card is inserted between the other two cards so that its
upper edge is close to the lower edge of the recess C₁, and the operative length of the
paper or linen strips a, Figures 1 and 2, which connect the lower edge of the middle
card, with the front card equal to the distance between the upper edge of the middle
card and the upper edge of the front card.
The upper edge of the back card is connected to the top edge of the front
card by paper or linen strips and with the middle card by means of a linen
strip d.
If it is not required that the middle card remains always parallel to the front card
the former may be connected to the other cards as shown in Figures 5 to eight. In
this case the lower edge of the middle card B is connected by a linen strip e with the
front card in the manner of a hinge while it is supported by the lower edge of
the recess of the back card through which it enters as shown in Figures 5 and 7.
A small band g connecting the middle card with the back card prevents the cards from
sliding out of the desired position.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A composite picture card consisting of a front card A, a middle card B and a bock
card C, in which the picture exposed on the middle card card and through the opening
of the front card or frame is illuminated by a light colour suitable to the nature of the
picture exposed reflected from opposite reflecting material of the desired colour on
the back of the front card.such reflecting material, receiving light through a recess of
the back card C.
