3. Portfolio.

Bound in leather and paper or cloth. Three boards are cut the same size. The joints between the boards are treated exactly like the back of a case binding, except that leather is used and that the inside of the joints are also lined up with leather. Small boards for the flaps are joined in the same manner to the ends of the middle board. Fig. 52 shows the portfolio with only the leather pasted on. The cover paper or cloth is cut and pasted exactly like that of the Library or Extra Binding.
