Specification Accepted, 27th Apr. 1859
I, JULIUS CARL WILHELM BACKE, of 26 Lindenstrasse, Stettin, in the Empire of
Germany Merchant, 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 :-
This invention relates to envelopes or wrappers which at the same time serve for
advertising purposes.
According to my invention the outer envelope or wrapper is made of transparent
material and it is provided with an enclosure of non-transparent material which
latter upon its outer side (and in some cases also on its inner side) is printed with
advertisements. These advertisements upon the non-transparent enclosure can be
read through the transparent cover, and are protected thereby from obliteration or
other injury. The advertisement enclosure is generally separate from the transparent
envelope or wrapper and is afterwards placed in the transparent cover.
In the accompanying drawing such an advertisement letter-envelope when
constructed and arranged according to my invention is represented in the Figures 1
to 4.
The enclosure consists of a sheet A such as is shewn at Figure 3, of non-
transparent material printed with advertisements, which material is of the same
length but double the breadth of the transparent outer cover which is designed for
the reception of the said onclosure. The hatched spaces (Figure 3) are intended to
indicate the advertisements which are printed on the said enclosure, the space a¹
remaining plain, and this space serves, when the sheet A has been folded about the
line XX and placed in the transparent envelope B, Figures 1 and 2, to make the
address, which is written on the said transparent envelope, distinctly visible.
At Figures 1 and 2 the enclosure A is supposed to have been placed in the
transparent envelope B and the hatched spaces representing the advertisements are
to be clearly seen; Figure 1 shews the addressed side of the envelope such address
being clearly visible on account of the plain space of the enclosure A coming under
the said address which is written on the envelope, and Figure 2 shows the fastening
ide or front of such an envelope.

page_text: The letter or other written or printed communication marked C is placed between
and enclosed by the enclosure sheet A, that is it is placed between the two halves a
and of the advertisement sheet A, and its position is clearly shewn at Figure 4
which is a section taken through the envelope B, enclosure sheet A, and letter or
other communication, C, and it will be noticed that there is no possibility of the
contents of the letter, C, being read through the transparent cover.
For the convenient laying hold of the enclosure when it is to be drawn out of the
cover, the half b of the latter is provided with a segment b¹ (Figure 3).
Figures 5 and 6 represent a wrapper made in accordance with my said invention.
Figure 5 shews the wrapper D, also consisting of transparent material in its unfolded
position with the likewise unfolded advertisement sheet A. The latter being provided
with a free space a' for the purpose of making the address clearly visible. E is
the newspaper or other matter which the wrapper D is to enclose. Figure 6 shews
in section the wrapper D folded round the newspaper or other matter E with the
advertisement sheet A lying between.
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 :-
The envelopes, wrappers and letter covers formed or made of transparent material,
with a non-transparent enclosure, on which are advertisements, for enclosing the
letter or other written or printed communication, the said non-transparent enclosure
having a free space to render the address clear and distinct, all substantially as and
for the purposes herein set forth.
