A SPECIAL camera is sold for making these little pictures.
[Illustration: FIG. 55.--STAMP CAMERA.]
It contains a number of lenses all of the same focus. In front is an
easel where the portrait is attached, surrounded by a suitable border.
The images given are about the size of postage stamps (see Fig. 56),
and when the negative is printed on a printing out or developing
paper, toned or developed, they can be perforated and gummed at the
back. They are very useful for sticking to letters, envelopes, and for
business purposes.
