John H. De Wild, Elements of show card writing (1923)
“ Pick out a brush that has a good even edge. A “ragged” brush is useless for heavy strokes. And when you find a brush that will work well, leaving the perpendicular and ends of the vertical lines even and neat, KEEP SUCH A BRUSH FOR THIS STYLE LETTERING, and use it for nothing else. In contrast to the “Egyptian”—a brush for the Roman alphabets must be pliable and of a “texture” to permit of light and heavy lines being made alternately.In forming the “Egyptian” the brush must hold its “chisel” edge, and keep an even stroke; therefore the necessity of using the right brush. ”
