Improvements in Advertising.
I, HENRY LOWENFELD, of Kops Brewery, Wandsworth Bridge Road, in the
County of London, Gentleman, do hereby declare the nature of this invention to
be as follows:-
My invention relates to advertising and consists in the use of cards or the like
having printed upon the inner surface of one of the sheets of the cardboard the
name or other matter forming the advertisement in such a manner that the sides of
the card when looked at in the ordinary manner are perfectly plain but that when
the card is held up to the light the words or design within the body of the card will
be visible. The surface of the card may have printed upon it words or designs
which may be read or viewed in conjunction with the words or design in the body
of the card or not as desired.
Dated this 21st day of July 1891.

COMPLETE SPECIFICATION.
Improvements in Advertising.
1, HENRY LOWENFELD, of Kops Brewery, Wandsworth Bridge Road, in the
County of London, Gentleman, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to advertising and consists in the use of cards or the like
having printed upon the inner surface of one of the sheets of paper, of which the
card-board is made up, the name or other matter or design forming the advertise-
ment, so that the cards when looked at in the ordinary manner are perfectly plain
but that, when the card is held up to the light, the words or design within the body
of the card will be visible. The surface of the card may have printed upon it words
or designs which may be read or viewed in conjunction with the words or design in
the body of the card or not as desired.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawing, in which, for
the purpose of illustration, I have represented a puzzle advertisement card made
according to my invention:
Figure 1 represents the front view or face of the card as it appears when looked
at in the ordinary manner, and in this case may be termed a puzzle:
Figure 2 shews the printed matter on the face of one of the sheets of paper of
which the card is made up; and,
Figure 3 shews the matter which appears when the card is looked at on being
held up to the light.
In practice the sheets from which the cards are to be made are printed with the
required design, ornament or matter as represented for example in Figures 1 and 2
respectively, and one of the sheets (Figure 1) is placed over the sheet represented
by Figure 2, and the two sheets are then pasted or otherwise connected together in
any suitable known manner.
By this means it will be obvious that I am enabled to produce a card which on
the face of it does not necessarily disclose an advertisement in any form, such for
example as the puzzle shewn in Figure 1, but when the card is held up to the light,

page_text: the matter forming the advertisement, such as that shewn in Figure 2, will appear
in addition to (and in this case forming the answer to) the puzzle on the face of the
card, as clearly shewn in Figure 3.
I am aware that cards or papers for advertising and other purposes have been
used having matter printed on both the front and back surfaces thereof and I make
no claim to such an arrangement.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A card or the like, for advertisement purposes, in which the matter forming
the advertisement is within the body of the card so that the advertisement is only
disclosed or made visible on the card being held to the light as hereinbefore
described.
2. The manufacture and use for the purposes of advertisement of cards, substan-
tially as hereinbefore described and illustrated in the accompanying drawing.
