The butterfly was a cut-out from a trade paper and pasted to the card-board.
In shading the letters on a showcard, or on any piece of sign work, the student should keep in mind the theory of shading which is as follows:
Imagine, if possible, that the letters to be shaded are about one inch in height from the paper and that a light is being held above and to the right of the letters at an angle of about 45 degrees. If this experiment is carried out in actual practice it will be found that the shadows fall to the left and below the letters. This is the rule for proper shading. The effect can be reversed by imagining the light coming from above and to the left. This would necessitate the shading on the right side of the letter and at the bottom.
Students should study the large cloth signs made by professional sign men, for splendid examples of shading.
