FIG. 91.—A DOUBLE. BY H. G. READING.
Some very amusing pictures can be made by double exposure. For instance, Fig. 91 represents a man playing cards with himself. A method of making these is thus described by W. J. Hickmott in "The American Annual of Photography for 1894":

FIG. 90.—FAREWELL RECEPTION TO THE PRINCE OF WALES.
FIG. 91, FIG 92, and FIG 93.
Fit an open square box into the back of the camera, having it fully as large as, or a little larger than, the negatives you wish to make. My attachment is made for 8 × 10 plates and under, and fits into the back of a 10 × 12 camera. In shape it is like Fig. 91, and I will designate it as A. The box is about 3 inches deep. When put into the camera it appears as in Fig. 92. Now have a plain strip of wood just one-half the size of the opening in A like B, Fig. 93. Have B fit very nicely in A, at the opening toward the lens, and so that it can be moved freely from one side to the other. It is very convenient to have a rabbet on the top and bottom of A so that B can be moved from side to side and maintained in any position.
