PROVISIONAL SPECIFICATION.
Improvements relating to the Production of Coloured Light Effects
in Christmas Cards and the like.
We, CARL HEYMANN and EDUARD SCHMIDT, both of 164 Schönhauser Allee,
Berlin, N., in the Empire of Germany, Manufacturers, do hereby declare the
nature of our invention to be as follows:-
This invention relates principally to ornamental cards similar to or suitable as
Christmas cards birthday cards or the like and the object of the invention is to
produce an artificial colouring of a pictorial representation by means of reflected
diffused light, whereby the natural colours of the picture are enhanced or special
effects produced by such reflection.
To this end we provide a front or facing card having an opening therein and
representing some optional device such as an open window, grotto or the like, and
behind this facing card to be set at a suitable distance therefrom we place the
pictorial representation to be illuminated, said pictorial representation being already
coloured or not as desired. On the back of the facing card are fixed strips or
pieces of coloured foil or tinsel, in the colours or arrangement desired so that the
fight reflected and diffused from the bright surface of these tinsels or foils
illuminates the picture in the manner desired.
Increased effect may be obtained by filling in cavities, through which light
passes to the tinsels or foils, by means of a transparent coloured medium such as
gelatine.
Such pictures will preferably be made to stand upright which may be done by
hinging the facing card to the pictorial card along the upper edge. There may be
slits in the rear pictorial card where same are not visible through the opening in
the facing card, for facilitating access of light to the tinsel or foils.
